This box is marked 800 , a mark used by many European Countries to denote their standard of Silver. Its 3" by 2 & 1/2" and 3/8" deep. I believe it was intended for snuff or possibly tobacco. It has a fancy design and the lid closes tightly. It has a hefty feel for a small box and is in great condition.
