This is a Showa-retro tin insect cage. It's quite old and has dents, paint剥がれ (peeling), rust, and dirt. It features nostalgic designs of beetles, butterflies, dragonflies, ladybugs, and more. This insect cage is a utility model and design registered product (see photo 14). I believe the registration is for this rectangular shape. Size: Height: Approximately 14cm Width: Approximately 15cm Depth: Approximately 8cm How about using it for interior decoration or as an object? For those who love Showa retro items, please consider purchasing it!!
