Available for immediate purchase. Set of water-based pens for sale. A mechanical pencil will also be included as a bonus. Since I'm unsure of the remaining ink in the water-based pens, I'm selling them at a low price. I've done a writing test in the second photo. The water-based pens include 3 of 01, and 1 each of 02 and 03. The transparent pens are 0.5, and are navy and black. (They are water-based pens from either Cainz or Muji) The bonus Snoopy mechanical pencil is a souvenir from Universal Studios Japan, but the top knock part is peeling off. The barrel is also heavy, made of iron? uni pin Pigment ink, water-resistant, light-resistant, extra fine, black Mitsubishi Pencil Co., Ltd. Rare, scarce, precious.
