These came vacuum packed and I was worried about the slight crease in the sides after opening pack. Sat overnight and looks good! Already have one on the turner! Pretty dense not flimsy at all! I'm happy with the purchase.

These work really well for the skinny tumblers. I haven’t tried the larger ones yet but I love the skinnies! They are soft but firm and don’t get stuck.

They came a little squished but not bad at all and they snapped right back after having them out of the package for a bit

Great for tumbler makers

Exactly what I needed so I can keep my tumblers turning.

These are perfect for tumblers and they fit a lot of different sized tumblers. They keep tumblers level which is super important! Definitely 10/10, will be purchasing more!

The foam inserts make using my spinners more reliable. No more do I worry about my tumblers falling off into the floor. The foam inserts hold the tumblers in place.

Great product. Highly recommended

Fits perfect on all of my cups!
