These are just what I needed for my girls [SEP] I have 3 girls who go through a bunch of pony tails. I was tired of spending $5+ on a pack of 10 ponty tails only for them to take them out and miss place them or loose them at school. So I was happy when I came across the 300 piece hair ties for such a great price. I wasnt expecting them to be durable or lasting. When I got them in I was surprised at how stretchy they were, which I love and they are very duarble. They are not thick like the ones I normally buy for my girls but they still get the job done and for the price I paid if they loose them or miss place them, its not such a big deal anymore.<br />I would recommend these hair ties to any of my friends
