Stored at home. Although unused, please consider purchasing if you understand that it has been stored by a non-professional for many years and may have deteriorated over time. The BW color pens are a bonus. These are old items and are not being sold as new. Please refrain from purchasing if you are concerned about aging, deterioration, or overlooked issues, as this is a non-professional inspection. Items will be shipped in simple packaging. I plan to dispose of the items if they don't sell, so your comments would be appreciated. Due to shipping circumstances, the shipping method may be changed from Rakuraku Mercari Bin to Yu-Yu Mercari Bin or vice versa.
