Uni POSCA PC-5M Paint Marker 1.8-2.5mm Medium Bullet Tip - Set of 8 Colors

Uni POSCA PC-5M 1.8–2.5mm medium bullet tip paint markers for bold art, surface decoration, and large-area craft work — set of 8 vibrant water-based colors.

The Uni POSCA PC-5M is the go-to marker when you need to cover more ground. Its 1.8–2.5mm medium bullet tip fills surfaces faster than the PC-3M while still offering enough control for lettering, outlining, and structured artwork. This set includes 8 colors: White, Yellow, Pink, Red, Blue, Light Blue, Green, and Black — a complete standard palette for art, craft, and decoration on almost any surface.

Key Features

• 1.8–2.5mm medium bullet tip → covers larger surface areas faster than fine tip markers → ideal for background fills, broad strokes, and bold lettering
• Opaque water-based pigment ink → vivid, solid coverage on both light and dark surfaces without bleed-through → colors remain true on paper, stone, ceramic, glass, fabric, and wood
• Shake-to-mix mechanism → press the tip to activate → consistent, smooth ink flow throughout the life of the marker without skipping or streaking
• Water-resistant when fully dry → artwork does not smear or bleed after drying → suitable for indoor display and light outdoor exposure
• Non-toxic, water-based formula → safe for all ages → no ventilation required for classroom, studio, or home use
• Set of 8 standard colors → covers primary, secondary, and neutral tones → a versatile foundation palette for most art and craft projects

Where You Can Use This

• Canvas painting — use as an alternative to acrylic brushwork for bold, graphic illustration and flat-color fills
• Rock and stone painting — the medium tip covers larger stones and pebbles quickly with solid, opaque color
• Ceramic and pottery decoration — ideal for filling large design areas on vases, pots, and tiles before adding fine detail with a PC-3M or PC-1MR
• Hand lettering, poster making, and sign writing where bold, readable strokes are needed
• Fabric art on canvas shoes, tote bags, jackets, and denim — great for bold graphic designs on fabric
• Wood and MDF painting — backgrounds, color blocking, and decorative surface fills on boards, frames, and boxes
• Glass and bottle decoration — the medium tip gives even coverage on curved glass surfaces
• Chalkboard and blackboard art — the opaque ink shows brightly on dark surfaces for menus, signage, and displays

Pro Tips

Before first use, shake each marker with the cap on, then press the tip on scrap paper 5 to 6 times to fully prime the ink — the medium tip holds more ink and may need a few extra presses. Use the PC-5M for backgrounds and large fills, then switch to the PC-3M or PC-1MR for fine detail and outlines. On non-porous surfaces like glass and ceramic, allow 24 hours of drying time before handling. Store horizontally with caps sealed to preserve tip condition.

Complete Your Setup

The PC-5M works best as part of a layered toolkit. Pair it with the POSCA PC-3M Fine Bullet Tip Set for detail work over broad fills, and the POSCA PC-1MR 0.7mm Extra Fine Set for outlining, lettering, and intricate patterns. A Smooth Painting Stones Pack or Black Cardstock Pad gives you the ideal surface to make the PC-5M colors stand out.

Frequently Asked Questions

Q: What is the difference between the PC-5M and the PC-3M?
A: The PC-5M has a 1.8–2.5mm medium bullet tip, while the PC-3M has a 0.9–1.3mm fine bullet tip. The PC-5M covers more surface area faster and is better suited for fills, backgrounds, and bold strokes. The PC-3M gives more control for detailed work and finer lines. Many artists use both together — PC-5M for fills, PC-3M for details.

Q: Can I use the PC-5M on canvas?
A: Yes. The PC-5M is well suited for canvas painting. Its medium tip covers canvas texture evenly, and the opaque pigment ink gives a result similar to acrylic paint but with the control and ease of a marker.

Q: Can I use these on fabric?
A: Yes. Use on pre-washed fabric and heat-set the dried ink with an iron using a cloth between the iron and the fabric. Avoid frequent machine washing after application to preserve color vibrancy.

Q: Are POSCA PC-5M markers suitable for outdoor use?
A: POSCA ink is water-resistant once fully dry and handles light outdoor exposure well. For long-term outdoor durability on surfaces like wood, stone, or ceramic, seal the finished surface with a UV-resistant clear varnish.

Q: Can I use the PC-5M on dark or black surfaces?
A: Yes. POSCA markers use opaque pigment ink, so all 8 colors in this set show clearly on dark or black surfaces. White, Yellow, and Light Blue are particularly striking on dark backgrounds.
