Hairties. What are they doing? Mostly getting lost or breaking or hurting.
I've seen foreign exchange students wearing these for sometime, and often thought that they'd be too loose to hold my hair, or just slip out, but I bought some recently and they're everything other hairties aren't!
They stay in! They slip out when you want them to! They don't pull your hair! They don't break! They're clear! They're strong enough to hold up a bun! They can be a bracelet that doesn't cut off your circulation!
You can get them off ebay here, or search for telephone hair band. Just make sure they're rigid plastic, not rubber.
