Oni Box NKUKU / Nkuku Small Size This is a glass case "Oni Box" from Nkuku, a British fair trade manufacturer. I purchased it about 8 years ago from a shop located within the Lake Ashi Terrace near Lake Ashi in Hakone. The product originally has a vintage feel. You can open and close the lid by sliding the knob on the front. Width: Approximately 22cm, Depth: Approximately 16.5cm, Height: Approximately 7.5cm
