Tunbridge Ware is famous for its micro-mosaic technique. Instead of painting or carving, the patterns are created by gluing together long, thin strips of differently colored woods into a block. The woodworker then slices thin veneers off the end of the block—much like slicing a loaf of bread—to reveal the intricate geometric or floral patterns, which are then glued onto the box.

Based on the style of the hinges, the escutcheon (the brass keyhole plate), and the specific geometric patterns, this box likely dates to the mid-to-late 19th century (approx. 1860–1890).
