STEM toy

These are so fun. My students love building and things and taking apart. This is perfect for me because I am always taking toys with me to work and it comes with a box that’s great for carrying. This is a great STEM toy to play with for a long time without getting bored.

Fun new open ended toy!! My 9 year old approves!

Really impressed. My 9 year old loves building and we felt had outgrown some open ended building toys like magnatiles and big blocks. She still plays with LEGO but isn’t quite ready for some harder toys like k’nex. She saw these on an ad and wanted them so we received them in exchange for our review. But I probably would have bought them either way because she really wanted them. I’m a teacher and toy guru. Ha! I don’t love that they’re made in China but it’s hard to find toys that aren’t. I also didn’t like that the guide just showed pictures but no basic instructions. In my opinion this is really for ages 5 or 6+ And would really frustrate a preschooler. My 9 year old said “write a good review mommy, this is fun.” She wanted to make a scooter right off the bat and after showing her one picture she got it. The pieces feel a bit thin and light weight so I was worried they’d break but even with lots of pulling and clicking and unclicking to build the scooter, none cracked or broke. So pros: -Comes in its own durable, clear plastic container with lid and handle. This alone is awesome! Toy storage is a pain. I love we can put this away in a closet and easily find it! -colorful -comes with a guide -open ended toy -creates big toys to use with dolls! Cons -made in China -guide doesn’t have clear instructions but didn’t bother my 9 year old I’ve added some photos too. We’d definitely buy more kits like this or expander kits.

Creative Skills

I like that there’s various colorful pieces and various pictures of things to make. I purchased this for my son’s 3rd birthday. Since he’s not in preschool or day care yet, I’m trying to purchase things to help with his development so that when he does begin school he can be on track with his class. I wish some of the pictures had images of the side, but it does allow us to use our imagination and be creative.

Cossy - Fun for everyone!

We recently had a retreat where I needed my preschooler to sit quietly for a few hours. Enter Cossy! I brought it out and she started building away! Then over comes my other kids one by one, even my 11 year old. And eventually kids I didn’t even know cane over to play. It comes with an idea manual for those that like to follow directions. But my preschooler enjoyed just building her creation which she called Spikey. I was concerned about the ends of Spikey snapping off when she took it apart but they are very durable!

So much fun

Love this set. Came in a sturdy case and my kids enjoy playing with them. Lots of open ended play. I don't like that there are only ball joints to put things together. For example you have to have a today and a ball to connect a wheel. It makes it look silly. But other than that it's great

Super inspirational building set, gets the imagination going!

Super mentally stimulating toy! Both my son and daughter love this building set. It has inspired them to make so many different things! They can’t stop playing with it.

Great STEM learning toy

Product was a gift for young grandsons who quickly figured out how to construct with the many varied pieces. Pieces snap together easily, stay together securely yet can be disassembled without adult help. Children love playing with this set and I can see how they are planning which pieces to use. It's a wonderful educational toy with a great value. Inexpensive, educational, and FUN! Also, Cossy has fantastic customer service. My question was answered within hours in a very courteous manner. I will be buying from them again.
