Love this product!
I have my own slim invisibobbles and think they are, hands down, the best way to hold my hair up (stays tight, no marks) and wear on the wrist when not in use (comfortable, doesn't get in the way, looks nicer than a black elastic bracelet). I purchased this item to give to my daughter, who had been coveting my invisibobbles.  We have different types of hair, and they work just as well in her hair, and on her smaller wrist.
