I purchased this as a spare about two years ago, but I'm selling it now because I no longer have a need for it. The current version on sale contains 20 sheets, but this is the product that was released before that. No individual sales. I will ship via Mercari's Nekopos service, including cardboard to prevent folding. Please understand that this item has been stored at home, and refrain from purchasing if you are looking for a perfect condition item. The price includes shipping and handling fees, so no price reduction is possible.
