This is a very rare, not-for-sale item. I obtained this small case a few years ago through a point exchange at a convenience store in Hong Kong. The material is plastic. Please refer to the photos for the size and color. It has never been used and has been stored in a drawer. There is a slight discoloration on the lid, but it's not very noticeable. If you are interested, please consider purchasing it. Also, it will be shipped in a 60-size box, and this price is set as the best price.
