The Uni-Ball Posca Pen features a 1mm - 10mm Flexible Brush tip loaded with highly pigmented, lightfast ink. This water-based ink is quick-drying, waterproof, and flows smoothly, allowing for easy writing on almost any surface. The ink is permanent on porous surfaces but can be removed from smooth surfaces like glass, metal, or plastic. Despite its dense and vibrant colour, it does not bleed through paper. Painting enthusiasts will rediscover all the pleasure of handling a brush combined with the unique qualities of POSCA, while beginners will learn new techniques quickly with no risks.

The brush tip is tapered to a fine point and ultra-flexible producing controlled brush-like strokes and shapes. Uni-Ball Posca Pens with flexible brush tips come in a variety of vibrant colours, allowing you to create the ultimate Posca pen collection.
