I buy a lot of stuff from Birchbox; almost everything I use on my face, hair, and body I've purchased from this site. These hair ties are THE BEST and most irreplaceable thing I have in my beauty world. You don't think a hair tie will change your life... until it does. I have thick, heavy, wavy hair and this keeps it up in a ponytail all day and doesn't budge even a little bit. I've given one to every one of my friends with long hair and they all love them. My best friend is Chinese and she has slippery, straight hair- she loves them. Another good friend has super curly but thinner hair- she loves them. I've even given a few to the girls I babysit who have long thick hair and they need to tie it tightly for sports- they love them! They look like a bracelet on your wrist, especially the gold/silver ones.
Everyone asks where I got them and everyone makes it a point to not lose them. I know $18 seems like a lot for something like this but it's so worth it!!
