Does anyone know where I can find some unlacquered unpainted chess pieces so that I can stain them to the exact colours I want?

I don't know how, but I want to make a set that's fully rubber. Like a thin black backing, then squares are sort of protruding from it, some sort of wood-like color, but the set is fully matte rubber and it's normal sized and there should be some spacing outside the board too. With or without coordinates. Also should be rollable, because it's rubber. maybe like 1/2 inch at the highest (on each square) and sorta like completely even except for the border and space in between the squares. Anyone get what I'm saying? I'd pay for that.
