These loom bands are clearly advertised as being "official rainbow loom bands with C clips" They are not official, not made by Rainbow Loom and do not contain c clips.
They are OK but I can buy these locally for £2.
The package states very clearly they are "Friendship" brand and contain S clips. I fail to see that this poor description was an error. The official Rainbow Loom brand bands are more expensive than this type, as I understand matters Rainbow is a small family-run company who had the initial idea for looms. I think it is a poor do that this company is cashing in on their success in such a way. Of course, from the product photo, you can't tell what brand they are and that should have warned me.
However, they arrived quickly and, as they were part of a birthday present, I was glad of that.
