I am selling this item because it did not fit the legs of my kotatsu. I am listing it as "Like New" because I only tried it on for size after purchasing it new. Please refrain from purchasing if you are sensitive to minor imperfections or are looking for a brand-new item, as it has been stored at home. This is a component used to adjust the height of table or kotatsu legs. You can choose from two heights by flipping it over. Please refer to the attached images for the applicable sizes. Height increase is approximately 3cm or approximately 6cm (reversible). Because the box is large, it will be shipped via Rakuraku Mercari Delivery (Takkyubin 60 size).
