Be creative with POSCA, the watercolor fineliner for unlimited application on all surfaces. Whether crafting, home decorating, or personalizing sports equipment, clothing, or accessories, the POSCA fineliner is the perfect tool. The water-based ink is odorless, adheres permanently to porous surfaces, can be wiped off smooth surfaces, and does not bleed through paper. The acrylic-like formula is opaque, covers well, and dries quickly.
