Onishi Seisakusho Slim Acetate Mechanical Pencil – Knock Type, Tortoiseshell Design, Japanese Handmade Stationery

---------------------------------------------------------------------- Specifications: 0.5mm type Material: acetate Size (approx.): 135 x 10mm Accessories: Case ★Nowadays, a variety of products are made from the petroleum-based resin "plastic," but Onishi Seisakusho uses an old-fashioned machine called a "potter's wheel" to carve each piece of timber out of a fiber-based resin called acetyloid (acetate), polish it, and carefully and meticulously finish it. This antique-style knock-type mechanical pencil is made with as many parts as possible made from acetate. The knock-type mechanical pencil is the same color as the main body, and the sound of the spring rubbing when you knock it to advance the lead is truly nostalgic. With craftsmen skilled in handcrafting writing instruments becoming increasingly rare, this will be a very valuable and rare piece. ★There are two types of thin and two types of thick shafts, but there are differences in the barrel ring part.
