Retro vintage pilot mechanical pencil. It's a twist-type pencil, so when you twist it, the 0.9mm lead comes out little by little, and when you twist it the other way, it retracts smoothly. It has a small, cute design that fits comfortably in your fingers when you hold it. The pale champagne-colored cap and black barrel are lovely. It has been disassembled and thoroughly cleaned, so it works very smoothly♪ When the lead runs out, remove the tip, turn the lead advance pin all the way to eject the remaining lead, then retract the lead advance pin slightly, insert a new lead into the lead chuck at the tip, twist to store the lead, and then attach the tip. It's an old-fashioned method, so it might be a bit troublesome. But on the other hand, you might feel a sense of romance (^m^) Twist mechanical pencil Pilot
