【Addendum】 This listing is now a dedicated listing for shin-chan-sama. - - - This is a discontinued drafting mechanical pencil, the Pilot H-1095. It uses 0.5mm lead. It is a product with a unique blue hue and a long knurled section. The knurling is not sharp-edged and does not hurt when gripped. I am listing it because I purchased it some time ago and have not used it. The knock mechanism operates normally, and there are no scratches on the barrel. The H-1090 series of mechanical pencils are known for the lead diameter print on the knock part peeling off easily, but as you can see in the photos, the print remains. I believe the condition is good, but please be aware that it is an old product. Shipping will be via Yu-Packet Post mini. Thank you for looking.
