Granted, I haven't used them long, but they are strong and keep their shape. Holds my hair securely.

I got these hair ties for my sister who has very long hair. She says they work wonderfully and don't pull or snag when she's tying up her hair. They seem to be very durable and stretchy without being too stretchy.

Best hair ties in years, finally a durable one

These hold up so much better than standard hair ties. Usually I can only use those for about a week before they break, these have been way longer lasting.

I used the hair ties to secure cupboard doors in the kitchen. I have several doors that will not stay shut. By combining two hair ties together, it stretches and allows the cupboards to stay firmly shut.
This was very easy and much better than using rubber bands.
