Makurabo x Showa Nishikawa Custom-Made Pillow Filling: Approximately 190g of "Zeoclean Pipe" Contains Zeomic, which is expected to have antibacterial, deodorizing, and antiviral effects. Use this to adjust the height yourself or to address any flattening of the filling. This is the filling from a pillow purchased in September on this site. The previous owner purchased a custom-made pillow around the spring of 2025 and replaced the filling at the end of July. The frequency of use after that until the time of listing (September) is unknown. After I purchased it, I checked the filling and found that it wasn't the type of pipe I preferred, so I stored it in a plastic bag after house cleaning. If anyone is looking for this, how about it? *Please note that a small amount of different pipes may be mixed in.
