For smoothing, unifying, and blending wax-based colored pencil strokes, try this handy double-ended blender pen from Speedball. The Finesse Blender features a brush tip on one side and a hard, round tip on the other side — so you can choose between soft, subtle blurring or firmer, more precise blending.
Acid-free, low-odor, quick-drying, and non-bleeding (we checked!), the Finesse pen is a great tool for anyone who uses colored pencil. Made in Japan.
