these are just what i needed for my girls [SEP] i have girls who go through a bunch of pony tails i was tired of spending on a pack of 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 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 anymorei would recommend these hair ties to any of my friends
