tombow mono twin permanent marker Colors:Blue A true collectors itemThis marker puts two different tips on one barrel a 0. 8 mm broad bullet tip for headers, labels, and bold outlines, and a 0. 4 mm extra fine point on the other end for small notes or detail work sharing a single ink reservoir so there's no second cartridge to manage. The ink is oil based and permanent, drying almost instantly and staying waterproof once set, which means lines drawn with it can be painted over with a water brush or water based marker
