Review (5/5): Great way to keep things on you when you don't have pockets
These are made well, and yes the zipper is on the outside but I easily flipped mine inwards without a fuss. I used one when I went to an amusement park the other day. I wore leggings with no pockets, and it held my chapstick and a few other tiny things. I wouldn't actually put this in my hair as it wouldn't tie evenly because of the items. Use another one for that and if you want to use an empty one as a hairtie it would work fine. But otherwise it looks like you just have a spare scrunchie on your wrist.
