Marker POSCA PC-5M by POSCA, pigment marker, khaki-green, round tip 1.8–2.5 mm, refillable

POSCA PC-5M by POSCA is a refillable pigment marker in khaki-green with a round 1.8–2.5 mm tip designed for writing, illustration and medium-detail artwork. The water-based opaque pigment ink provides uniform, matte coverage on porous and non-porous surfaces, adheres well to paper, wood, metal, glass and many fabrics, dries quickly and becomes water-resistant when dry. The refillable construction supports longer-term use while the medium round nib balances line control and coverage for general creative and functional tasks.

Advantages

The POSCA PC-5M marker uses opaque pigment ink that offers consistent color density without strong odor and resists fading after drying. Its 1.8–2.5 mm round tip produces reliable medium lines suitable for lettering and illustration, and the refillable body reduces the need for frequent replacement. The water-based formulation makes cleanup from many surfaces easier before drying, and the pigment composition ensures better lightfastness and permanence compared with simple dye-based inks.

Suitable for

• Hand lettering and signage on paper, card and board
• Medium-detail illustration and sketching
• Craft and DIY projects on wood, ceramic and glass (decorative use)
• Marking and labelling on metal and plastic surfaces
• Textile decoration for non-washable or fixed fabric items (test first)

When it may not be suitable

This marker is designed for medium-detail work; if you require very fine lines below 1.8 mm or broad coverage above 2.5 mm in a single stroke, a different nib size is more appropriate. While the ink becomes water-resistant once fully dry, it is not intended as a permanent industrial coating for frequently washed textiles or surfaces exposed to heavy abrasion without additional sealing.

Key specifications

• Ink type: water-based opaque pigment
• Tip: round nib
• Line width: 1.8–2.5 mm (medium)
• Color: khaki-green
• Refillable: yes
• Suitable surfaces: paper, wood, metal, glass, some fabrics, plastic
• Drying behavior: quick-drying; water-resistant when dry

How to use

Shake the marker well before use to mix the pigment. Press the nib gently on a test surface until the ink flows evenly, then apply with steady strokes. For non-porous surfaces, work in thin layers and allow each layer to dry to achieve opaque coverage. If using on textiles, test on a hidden area first and consider heat-setting or sealing depending on the fabric and intended use. Refill following the manufacturer's refill instructions when ink runs low.

What to consider before purchase

• Confirm that the 1.8–2.5 mm medium round tip matches your required line thickness
• Test adhesion and permanence on the specific surface or fabric before final use
• Consider whether a different POSCA nib size is better for finer or broader work
• Refill availability and refill procedure if long-term use is intended

Usage recommendations

Store horizontally with the cap securely closed to maintain nib condition. For best results on non-porous surfaces, allow adequate drying time between layers and avoid heavy mechanical abrasion; for fabrics, perform a test wash or use a recommended fixative if the item will be laundered.
