These fit inside the mouth so are not safe for young children. Bought for a toddlers party - none of the 12 toddlers liked them. Good price but need to be bigger in size as these were a waste of money for us.
They were a lot smaller than I was expecting which meant that they weren't appropriate to give to the younger children at the party but they were bright and the other children loved them. They can really quickly as well which was good.
