Very similar to Mondo, but a slicker finish. These blocks will last for years. Kids can throw them, knock them down, stand and jump on them. They are pretty indestructible. I've been giving these to my kids, their kids, and lots of other folks' kids for about 30 years. Can't beat 'em. Great for developing math skills directly and indirectly. You do have to figure out where you're going to store them, and be ready to have them all over the floor. If you can't stand the mess kids make, don't get these (and perhaps reconsider having children).

These blocks are a wonderful addition to our playroom! My two year old son loves stacking and knocking them over, and I love that they aren't hard enough to damage anything, but sturdy enough to handle a two year olds abuse. When I first opened the package, I was a little confused as to how these blocks were to go together, but the instructions included were very thourough, and easily explained how to get the blocks folded just so, so they'd be as sturdy as they needed to be. I built all 40 blocks by myself (while my two year old grabbbed the finished ones from me) in about 45 minutes, so they aren't as terrible as you may first think. There is assembly, but it isn't difficult at all. Out of all 40 blocks, only one has been crunched, and that was due to it being stuck under the recliner when my husband flopped down into the chair. Otherwise, these blocks are plety sturdy for a childs rough play.

My wife recently bought these for our 4yo. He has a very heavy hand and there are not a lot of poorly produced items that make it through a day with him. He loves to build and my wife wanted to get the blocks we used to have in kindergarten. While these aren't exactly the same, they are pretty close -- close enough that it really doesn't matter. He loves them. He builds castles, chairs, and trains. He sits and stands on them. A few show some wear, but they have mostly held up well. I love them and have thought about ordering a second set for him.

I'm an adult who bought these bricks for her 2-year-old nephew, but I'll admit to occasionally fantasizing about buying 50 sets and making huge forts in my apartment. My kindergarten class had a similar set of bricks and I remember always being frustrated that they didn't have enough. I could finally resolve that childhood trauma! The blocks themselves took about 15 minutes to assemble with 3 adults working on it. My nephew absolutely loved them. He's the kind of kid who loves to stack things, line them up, and generally organize everything. He also LOVED playing Godzilla and knocking down the forts we adults would build. My sister (his mother, an early childhood teacher) also pointed out that they're great for his motor skills. As the towers would get taller and taller, he'd have to use a steady hand to keep everything from falling over. Sometimes it worked, and sometimes it all fell over. It's a fun way to learn. The only real complaint is that the package has a ton of little bricks and very few of the big ones. To make anything really cool, you need a few packages, and that can take up quite a bit of space if you live in a small home. If you want more big blocks (or just more affordable blocks), another alternative is to search Amazon for "white shipping boxes". White ones offer a blank drawing surface so your kids can decorate the "bricks" themselves. Just get some clear packing tape and seal the boxes (or get corrugated mailers that stay in a box shape on their own).

My grandson’s love these blocks ! We have two sets and have built a fort, a castle, and an obstacle course. They are holding up really well considering both boys (18 months and 3 1/2 year old) are very active and love destroying the things they build as much as making them. Definitely will buy more!

I worried when I purchased these that they might be flimsy, difficult to assemble, or cheaply made with too many yellow blocks. After a few months with them, I can safely say that they've exceeded my expectations. They do require assembly, but they all fit together in the same fashion. The first two or three might take you a while to figure out, but once you have the pattern down, you can move really quickly. The first blocks might have taken me 5 minutes each to put together, but then I was doing them all in 2 minutes or less each (all sizes - all colors...they're all really the same basic folding design). These are strong, and solid. The coloring on them holds up well. They stack well and are solid cardboard. This means your kid can stack them up and knock them down as much as they want and they'll stand up to the play. There are fewer red bricks than blue or yellow, but that wasn't an issue for us. Kids aren't architects, they just to stack stuff and knock it over...and it doesn't matter which blocks I use to do that - it's still fun for them. This container has 40 blocks in it. That's more than enough. When you've got a dozen or so folded up, they take up a lot of space, so you just keep the rest for replacements. However, it has been a few months and none are worn out or broken. Now that I've got a daughter who's approaching the age to play with these, I'll be using the existing blocks and those left unfolded still will be used for her enjoyment. High quality. Fun to play with. Will probably last longer than your child's interest in them.

I have 3 kids, ages 11 yrs,7yrs,and 2years old. These Melissa and Doug blocks are something I have always wanted for my kids,but never bought. (Until now!) I first saw them years ago when I started teaching preschool. The preschoolers always loved these blocks! They were one of the first toys chosen every day. Well, I finally purchased a set for my own children. I'm so glad I did. I really only expected my 2 year old to play with these, but all three of my kids actually play with these. These blocks are surprisingly durable for being made from cardboard. They are flat for shipping, and need to be assembled. I put them together by myself during Naptime one day. It was simple. No tools, or adhesive needed. They fold up securely creating 3 sizes of blocks in 3 colors. The yellow block measures 6x3x3.The blue block measures 6x6x3. The red block measures 12x6x3. These blocks do require some space for storing. We have been keeping these on the bottom two shelves of a book shelf. However, stacking in a corner of a room would work just as well. I'm so glad I finally bought a set of these. All three of my kids are enjoying these jumbo blocks by Melissa and Doug.

If you google block playing you will find a ton of articles about how important playing with blocks is to a child's development. So, we wanted to have blocks in the children's room at the library. We love these cardboard blocks because children can play with them without making noise, and won't get hurt if one is thrown--kids do have library tantrums sometimes. There are 8 large red bricks, 8 medium size blue bricks, and 24 small yellow bricks. The children do play with all of the sizes. We actually have two sets for group play. I might prefer more of the larger bricks, but the variety is definitely good--wouldn't want ALL large bricks. They come flat. An adult has to fold them, which is not at all difficult; I didn't even read the instructions. One reviewer said his children crushed them in just a few hours. I can only think that their bricks were not put together correctly. Our library kids stand on them all the time, and they are still in perfect shape. One thing I don't like about them is that Melissa & Doug put their name and phone number on every block. That's just cheesy to me. If you keep them stacked up neatly, they don't take up much space--and the kids are pretty good about keeping them neat because stacking them up against the wall is kind of fun. They even seem to feel compelled to sort them by color. Also bought these for my niece and nephew, and they work out well at home, too. Hint: Amazon puts these on sale on Cyber Monday some years.

My son (7) loves these. I ordered two so he could build a castle with them and he does quite frequently. He has battles and will pretend he is in minecraft. Just be mindful if you have a stupid lug-nut black lab. She will eat them and leave shards of cardboard through out your house like the remains of a fallen warrior.

These are great. Easy for 1 or 2 parents to team up and construct quickly, they stay contsructed even when stood on by my toddler. There are 40 blocks (as the package says), we thought that would not be enough and almost ordered two sets, but let me tell you, you can build quite a few things with 40 blocks, and they take up a lot of room. Being an engineer myself, I appreciate the proportions of each size block match the other blocks, i.e. 1 red block is as wide as 2 blue, and 4 yellows. This makes building quick and fun structures much better, and more stable as the blocks leave minimal gaps. My son loves to build with these on his own, but loves when I build a super tall tower (~7 feet-ish) before letting him run through it seeing it all crash down. There's actually quite a bit of learning that a kiddo can get from some simple blocks. I'd get these again in a heartbeat.
