I am not an end-user and do not have detailed knowledge, so I am not sure of the specifics. The items have been stored for a long time, and the box and figures have storage-related stains (discoloration?) and dust. Please review the images carefully before bidding. ☆ I am an individual seller, so there is a possibility of overlooking scratches, stains, and functional defects. For machinery and other items of concern, I recommend inspecting them in person to confirm their condition. ☆ For electrical appliances, even if the item's operation has been confirmed, it may be inferior to its original functionality. I recommend inspecting the item in person and confirming its operation yourself. ☆ No price reductions. ☆ I generally do not clean the items. They are sold as-is. ☆ Replies and shipping may be delayed on weekends and holidays. ☆ I am also selling these items elsewhere. Please consider purchasing them early if you are interested. ☆ Please feel free to ask any questions.
