Junk
These do not work.  They are not long enough to bend the ends over to hold the wrapped hair in place.  In addition, the foam is so thick, which is what I wanted for a large curl, that the wire inside isn't strong enough to hold it anyway.  The small ones work but make a tight curl. This is just a failed design.  Don't waste your money, seller won't refund it but Amazon will if you go to the trouble to ask.  If I could give zero stars I would.  These will go in the trash.
