I like this scrunchies, they are thinner and the rubber band ist wider than usual. Just not sure about the sleeping and the hair breakage part, if this makes a lot of difference to other scrunchies? I would say they’re good, but I’m not overly impressed as being the NBT. 

Prevent the breaking of the hair. Perfect!

The scrunchies are fine. You get a set of different colours so that's nice.

I have fine hair with a sensitive head and these are some of the best bobbins I have come across. They don’t pull at your hair and they haven’t lost their shape/elasticity unlike other more expensive brands. Have bought in both black and blush. Also found them cheaper on this site compared to my local shops which was another plus.

these are perfect for messy buns, or to tie your hair into a braid for sleeping. wonderful scrunchies!
