ZIG Art & Graphic Twin RB+F
ZIG has re-mastered their most notable double-ended marker into a totally new one: introducing the Art & Graphic Twin RB+F by Zig! The “RB” stands for “real brush,” because one side of this marker has an actual brush tip. The opposite side has a thin 0.8mm felt tip, or “F” for short. The blue ink in this marker is water-based, so you can dip the brush tip end into water to achieve a greater watercolor effect.
