What do you dip cake pops in?

they are mostly dipped in candy melting wafers, made by Wilton, in america they are sold in quite a few places but in England they are sold in cake decorating shops and i have seen them in Hobbycraft. they come in a range of colours.

i have also dipped them in runny royal icing, they come out very hard and crunchy though, not to everyone's taste...
