【Extremely Rare & New, Unused】 This is a custom mechanical pencil based on the Pentel PG5, made by Sharp Tank. I am selling it to organize my collection. After purchase, it has never been taken out of the box, nor has it been test-written on, so it is in "completely unused" condition. It has been carefully stored in a dark place. 【Specs & Features】 • Grip: Titanium lattice grip • Shaft material (wood shaft): Blackwood or Rosewood (I'm not certain, as it's based on my memory at the time of purchase, so please understand. It is a very heavy, dark-colored natural wood. Please judge from the photos.) • Color: All black 【Condition】 • Condition: New, Unused • Storage condition: Stored in a dark place. It has not been displayed for viewing. • Accessories: All original packaging, etc., are included. I believe this is in top-tier condition, both for practical use and as a collector's item. ★Bundling is a great deal★ I am also selling other rare writing instruments from Nohara Kogei, Kobo Kuse, etc. #Tonpei's Stationery Collection If you purchase two or more items at the same time, I will offer a discount on the shipping cost + α. If you wish to do so, please let me know in the comments section before purchasing. 【About Shipping】 Due to the high value of the item, I will carefully package and ship it. 【Notes】 I bought this at first sight, so I don't have sufficient knowledge. I would appreciate it if someone who can judge from the photos would purchase it.
