STG Silver spectacles case

Hello all at ganoksin

I’ve been asked to supply a sterling silver glasses case. Does anyone
know of a company that makes solid not plated silverware who may have
one in their range. It must be plain not engraved with any pattern
and about the size to fit a medium pair of sunglasses. I can hand
make it myself but I am extremely busy and was hoping to avoid it. I
have looked on the internet quite a bit and could not find one. Any
advice would be much appreciated.
