Fit for purpose. My daughter has a LOT of fine hair, so for everyday pony tails etc these are no good - she just has too much hair. We have tried a couple and even with a single plait we've struggled to get it over the extra bit without it snapping. But they are handy for smaller jobs where she just needs to tie small amounts of hair, such as the end of multiple plaits, or for smaller sectioned bits of hair. They can usually be used a couple of times, but stretch pretty quickly. Luckily we don't use a lot, so I don't get too hung up on the less-than-desirable environmental aspect of these, as a pack will last a long time.
