You don't have enough of one or two Gomee? Why not getting the complete collection? 

Gomee is a collection of eraser figurines to assemble and collect.

Each character from the Cinereplicas Harry Potter Gomee Collection has to be assembled and has its own accessories that can be added and interchanged.

They are made of rubber and actually work as a rubber! They will be a fine addition to your stationery set.
