These are sturdy pretty hair Ties that don't 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 thin..not luxurious..but I still like pony tails and products that not damaging to hair! I'd would like a smaller diameter..they don't have to be narrow..the 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.
