＜New, Unused 19-Piece Set＞ These items were unpacked and stored, but are new and unused. I intended to use them but never got the chance, so I am offering them at the lowest possible price to someone who understands they have been kept at home. Please refrain from purchasing if you are looking for perfection. Addendum: I used one of the 20-piece set and stored the rest. I am listing the remaining 19 unused pieces together. To ensure a smooth transaction, please be sure to read my profile. The following is quoted from the website.
