Pro Tips

Before first use, shake the marker with the cap on, then press the tip on scrap paper 4 to 5 times to prime the ink flow. For work on non-porous surfaces like glass or metal, allow 24 hours of drying time before handling. Layering is possible once the first coat is fully dry. To protect finished work on porous surfaces, seal with a matte or gloss varnish spray.

Complete Your Setup

Pair these markers with a Black Smooth Cardstock or Mixed Media Pad for maximum color contrast. Add a set of POSCA Brush Tip Markers (PC-5M or PC-7M) for broader fills and backgrounds. A Pencil Sketch Set helps you plan layouts before inking. For rock and stone art, a pack of Smooth Painting Stones rounds out your setup.

Frequently Asked Questions

Q: Can I use POSCA PC-1MR markers on fabric?
A: Yes. POSCA markers work on fabric. For best durability, use on pre-washed fabric and heat-set the dry ink with an iron using a cloth between the iron and the fabric. Avoid frequent machine washing after application.

Q: Are these markers permanent once dry?
A: On porous surfaces like paper, cardboard, and stone, the ink becomes permanent once dry. On non-porous surfaces like glass, plastic, or metal, the ink resists light moisture after drying but can be removed with water before it fully cures.

Q: What is the difference between PC-1MR and PC-1M?
A: Both are 0.7mm extra fine tip markers. The PC-1MR has a pin-type metal-reinforced tip which is firmer and more precise, making it better suited for very fine linework and detailing. The PC-1M has a slightly more traditional plastic fine tip.

Q: Can I use these on dark paper or black surfaces?
A: Yes. POSCA markers use opaque pigment-based ink, so colors like White, Yellow, and Pink show clearly even on black or dark surfaces. This makes them popular for dark paper art and chalkboard-style projects.

Q: How do I clean POSCA ink from surfaces or skin?
A: Since the ink is water-based, it washes off skin and unintended surfaces easily with water when still wet. Once dry on non-porous surfaces, it can be removed with a damp cloth or rubbing alcohol.
