A charmer of a tiny box, and certainly a very old one, carved of pine with a fantastic patina now, and found with a handful of old ink pen nibs inside. It looks, at least to me, that the box (excepting the sliding lid) was carved from one piece of wood, but due to a split along one edge a couple of tiny nails were added as reinforcement. Though there's been a bit more minor splitting since, but it's held up well, as the slide top slides easily and holds well. 

3 1/16" l x 1 1/8" w x 1/2" t. Nibs included!
