Due to the shooting environment, there may be errors in the actual color of the item. The listing may be removed without notice. The shipping method may be changed from Yu-Yu Mercari Bin to Raku-Raku Mercari Bin after purchase. Measurements are taken by amateurs, so there may be slight errors from the actual size.

Please refrain from considering or purchasing if you are particularly sensitive or have excessive expectations or particular preferences. I try to use recycled cushioning materials and cardboard, and I aim for simple packaging that does not affect the product. I am listing items with consideration and care, thinking from the perspective of a buyer. I hope that we can have a meaningful transaction for both of us and for the items themselves.
