Posca Extra-Broad Yellow, 3 pens Total: 3 pens ⭕️ These are extra-broad type pens with a writing width of 18mm, with a list price of 500 yen (excluding tax). Posca is a sign pen (or felt-tip pen, water-based marker) using water-based pigment ink, sold by Mitsubishi Pencil. The label on the body says "Poster Color Marker." Overview It uses opaque water-based pigment ink, which produces vivid colors like poster color (a type of paint), is water-resistant after drying, allows for over-writing, and does not bleed or transfer to the back. Being water-based, it does not damage materials. Initially intended for drawing on paper, as a sign pen suggests, the pigment ink also allows writing on metal, glass, plastic, etc. ⚠️ The thickness is barely within 3cm, so I will ship it as is in an envelope. Last time, even though I shipped it by Nekopos (210 yen), it exceeded 3cm, and the shipping cost was automatically changed to 750 yen. Please understand and purchase accordingly.
