I have taken it out of the box, but the contents are unused. I am selling it because I will not be using it. It has a moderate hardness and can be autoclaved. This is a single item for sale, but I have multiple unused items, so please feel free to inquire. I will offer a discount depending on the quantity. Due to the product price, this item will be shipped via Nekopos. Thank you for your understanding. [Retail Price] ¥10,890 Please see below for product details. http://www.ydm.co.jp/dental/post-78.html * For dental and orthodontic professionals, and others. * No claims and no returns, please.
