You mean just the wood? Or you want cases already made of wood?
If just the wood, PG veneer or any non PG veneer ought to work… just cut it to size?
Or wait, you mean the plastic case part?
So originally I just meant the plastic case part because it honestly never occurred to me that I might be able to purchase bulk cases with the wood already attached. The pre-constructed ones are worth considering, though I’m immediately concerned about the quality of the wood (or more likely wood-like substance) and the potential for fume issues.
Adding the word “wholesale” to the search has lead me down some more productive paths.
I’d still welcome additional resources and really appreciate everyone’s feedback so far.
