How Long Does a Posca Marker Last?

The longevity of a Posca marker depends on several factors, including tip size, frequency of use, and surface type. Here’s a general guide:

• PC-1MR & PC-1M (Fine & Extra-Fine Tips) – Best for detailing, fine lines, and hand lettering. They last for several months to a year with regular use on small-scale projects.
• PC-3M & PC-3ML (Medium Fine Tips) – Used for outlining, small drawings, and layered artwork. Can last 6 months to a year with frequent use.
• PC-5M (Standard & Metallic Colours) – The most versatile medium bullet tip, great for bold outlines, filling in spaces, and mixed media art. Lasts several months with consistent use.
• PC-7M & PC-8K (Large Bullet & Chisel Tips) – Ideal for poster work, murals, and larger-scale art. Expect them to last a few months with heavy coverage.
• PC-17K & MOP'R (Extra Broad & Mop Tips) – Used for large murals, graffiti art, and sign-making. These markers hold large ink capacities but get depleted faster when covering bigger areas.

Maximising the Life of Your Posca Marker

To get the most out of your Posca markers, follow these simple maintenance tips:

✅ Shake Well Before Use – Ensures the pigment is evenly mixed for consistent colour flow. ✅ Press the Tip Gently – When activating a new marker, press gently on scrap paper to avoid ink overflow. ✅ Store Horizontally – This keeps the ink evenly distributed inside the pen, preventing blockages. ✅ Clean the Nib Regularly – Wipe with a tissue if clogged and rinse with water if needed. ✅ Use the Right Tip for the Right Surface – For smoother surfaces like glass or metal, finer tips last longer; for rougher textures, opt for broader tips.

Are Posca Markers Refillable?

Posca markers are not refillable, but they are designed to be used until the very last drop. If your marker stops flowing, try:

• Shaking and reactivating the tip by pressing it a few times.
• Soaking the nib in warm water to remove dried paint.
• Replacing the tip (available for some models like PC-1M, PC3M, PC-5M and PC-8K).
