Opened for the purpose of taking photos, but unused. There may be some aging degradation of the rubber. If you don't need the box, I will discount the shipping cost. ※※※※※※※※※※ I am currently visiting my parents' home for the birth of my child, and I have a child who is less than one month old. I am temporarily selling unwanted items from my parents' home, but I will delete all items currently listed around April 3rd. If you have a product you are interested in, please purchase it as soon as possible. Also, used items from my parents' home have a lot of aging degradation, so I have priced them as cheaply as possible. Please understand that I cannot offer significant discounts. I have set a generous shipping deadline, but I may be slow to respond or ship due to childcare for a young child. I may not be able to respond in some cases, so it would be smoother if you leave a comment. Please purchase only if you understand.
