※ Please read this carefully before purchasing, as important information is included. This is a custom pen shaft I made for mechanical pencils. (Please understand that this is a handmade item.) This is not a Pentel genuine product. [Shaft Only] Sold as one piece. (If you contact me before purchasing, I can sell it with other colors, etc. I will discount 300 yen or more for those who buy multiple shafts.) Made with a 3D printer. (There are layer lines unique to 3D printing.) Shaft diameter is approximately 10mm. This is made to order, so it will take some time to ship. Please understand. (It is listed as up to 7 days, but I usually ship within 3 days.) White color can be changed. The shaft only will be wrapped in bubble wrap and sent in an envelope. (Can be changed to Rakuraku delivery)
