Purchased new over 10 years ago, never used. The condition has minor scratches, and the material tends to attract dust. Originally part of a set, now sold separately. Instruction manual not included. Washed with detergent. Still perfectly usable. Outer dimensions: approximately 20 x 6.8 cm. Please allow for some error. No price reduction. I also have other Asahi Kasei products for sale. Will be shipped in a plastic bag, bubble wrap, and an envelope or cardboard box via Nekopos or Yu-packet Post. The shipping method will be chosen without prior notice. Please read my profile to avoid any issues. Thank you for looking.
