“I LOVE the blue marbling first of all. It looks so cool. (The frosted white i got for a friend is nice too) I got this for my son (in anticipation of him getting older) and ONLY bc my friend wanted this stuff for her bday and I wanted to get to free shipping so why not try out this brand. It is all really cool stuff! The silicone is nice and firm and does not look or feel cheap (I got her white marble w black lid and it looks really sharp). My son is only 9 months but teething like crazy and liked chewing in his cup (I didn't see any dents) so I can see how I once saw a promotion for the shot glass size as teethers. My friend is so excited to use everything I got her too.”
