In Central European folklore, Krampus is a horned, anthropomorphic figure described as "half-goat, half-demon", who, during the Christmas season, punishes children retailer who have misbehaved...or to put it another way, a Krampus is a bad ass death metal Santa who will come for you if you are naughty!
3 inches tall (but can be custom sized), etched into copper, and then darkened with a patina. Comes in two versions, dark and light, basically mirror images of each other.
Adorn your bicycle with this awesome folk legend, comes in dark and light versions.
