Most of the characters on the Kawaii hair ties are just too big. As an adult who already looks very young, I want to be able to have the whimsy without being mistaken for a 12 year old constantly. These hair ties are perfect. I love wearing them both around my wrist and in my hair. After repeated use they do start to stretch and break, so you'll need to replace them with some frequency, but I like them enough that it's worth it. I don't usually buy Sanrio products, but I can't find any of the other characters in this kind of hair tie any more, so Sanrio it is!
