Dave Hakkens has finally come up with a pen it is ok to chew on; this one is made entirely of candied sweets.
The type of sweets used have the same texture of candy bracelets and do not stick on anything or melt while in your hands. The pen contains 22 pieces and is filled with edible ink. The only thing which is not edible is the small point where you write with. When finished you throw it away or put in in a new re-fill pen.
I might do more work now I can combine it with snack time.
