Teether key release.

Keychain Key nice solid plastic but not breaking with anti-slip material for a secure grip by babies.
The colors are pleasing to the eye and the ring is oval and wide enough so that keys can easily move independently of each other. Anything can chew without fear. The gel filled portions are flexible, transparent and full of bubbles, that's great. This part of the key hardens when refrigerated and it is true that they remain cool long enough but it's not necessarily that part where the child will put in his mouth because small thus discovering putting everything in their mouths goes! And I noticed that this is the ring that is chewed more often, so I think the ring should be also made in the filled gel material. But hey, it's a good product, good quality.

One small problem though: the ring in question, because of its anti-slip material hangs a little lint and dust lying around .... while there is none on the freeze key part.
