This item was released in 2010. The supplement is unused and unopened, but the book shows signs of creasing, staining, and deterioration, so the condition is listed as "Like New." Although unopened, it is quite old, so the presence or absence of deterioration cannot be guaranteed. Please understand this before purchasing. ⚠️ We are unable to sell the supplement separately as it is unopened. If you are interested in purchasing and need to check the contents, we will allow you to open it for inspection. Please feel free to ask.
