Bought as a gift for my 13 year old son for his birthday. He loves it. Unfortunately, it was tangled beyond repair in less than week. If it had been a bit sturdier, I don't think it would have tangled so badly. I'm glad it was cheap.It came broken and we couldn't return it because the return window was very short.Just needed tips to do my nails read the reviews and decided to give these one a try and they seem good enough can’t wait to try them.amazing packaging and comes in a variety of sizesI give it zero star. Too curvy that won’t sit on my nails.
