You can get your very own Lucky Tooth in the shop - I've just put them in!
Each one is as one-of-a-kind as a real tooth (but most measure about 1" tall).
I think these will be wonderful as gifts for friends for whom you wish a spot of good luck. Or, you could to slip into your own bag when you, yourself, need the spot of good luck (thinking job interviews, etc).
Silly little things like these make me so happy!
