Large Wave Crest hinged jewelry lock or locking box or casket made by C. F. Monroe. The box is about 5.5 inches wide and 5.5 inches tall when closed. It is about 8.75 inches tall when the lid is open.
This is a locking box but there is no key and no way to know if the locking mechanism is intact or workable. The lining has fraying and a hole and there's a small factory dent in the glass on the lid.
