When I was making Isabella’s Treasure box, the size was so small that I couldn’t find any pre-made hinges, so I had to make them myself. This set of L-hinges measures only 18mm long by 5mm wide by 2.5mm thick, with the wide part of the L measuring 10mm.

It was a real 3-D puzzle to plan out the mortises for the hinges on one side and the sliding door grooves on the other.
