Recently, we've started selling on another site, so although extremely rare, there's a possibility of simultaneous purchases. In such cases, we will prioritize the first purchase, and the later purchase will be canceled. Thank you for your understanding. Price negotiations are not accepted. A thin piece of stabilizing material that I was able to win on Yahoo Auctions a while ago. The thickness was insufficient to use as a blank material as is, so I cut it in half, corrected the warping, and then pressed it to create a blank material. There is a compression mark in the center due to the compression material, but there is no problem with the strength. See images 4 and 5. The metal fittings in the images are for photography purposes, so they may not be properly inserted or may have scratches, but we will ship with new metal fittings. Please see them as an assembly image. The size is approximately 140mm in total length, approximately 9mm at the pen tip, approximately 13mm at the maximum diameter, and tapers to approximately 9mm on the clip side. The weight is approximately 21g, and it is a single-action type without a guide pipe. Also, you can choose the core size and the color of the metal fittings. The metal fittings are gold or chrome, and the core is 0.5mm/0.7mm. If you do not select, we will send 0.5mm gold.
