these are sturdy pretty hair ties that do not damage hair [SEP] i really like these and the concept behind them but i wish you would make some that are much smaller in diameter for those of us with sadly thin hair my hair is thinnot luxuriousbut i still like pony tails and products that not damaging to hair i would would like a smaller diameterthey do not have to be narrowthe fat coils will stay in thin hair but they need to be a size small and marked as such i looked thru every similar item listed before buying these offer some smaller ones for skimpy haired ladies and children with thin hair and i will buy more
