Uni POSCA Mop'R Marker, XXL (3-19mm), Water-Based & Multi-Surface, White – Pack of 4

This marker is formulated for multi-surface use. It writes well on paper, cardboard, wood, fabric, plastic, metal, glass, ceramic, canvas, and other common craft surfaces. It’s especially effective on dark or colored backgrounds due to its opaque white ink.

Key specs: tip range 3–19 mm (versatile for fine lines to broad strokes), water-based and non-toxic ink, smooth and consistent application, quick-drying formula to prevent smudging, rich opaque white ink, suitable for a variety of surfaces, and packaged as a pack of 4.

Shake well before use. Remove the cap and prime the nib by pressing it gently onto scrap material until ink begins to flow. Test and then apply with even strokes. After use, recap the marker to prevent the tip from drying out and store upright between uses.

The ink dries quickly on most surfaces, typically within minutes. To avoid smudging, let the ink set before handling and avoid touching the surface until fully dry. Drying time can vary slightly based on surface texture and ambient conditions.

Yes. The Posca Mop'R markers use water-based, non-toxic ink, making them suitable for arts and crafts, including use by both adults and older children under proper supervision. Always follow product safety guidelines on the label.

Use in a well-ventilated area. Recap after use and store upright. Avoid prolonged skin contact on sensitive individuals, and keep away from small children who are likely to put markers in their mouths. If ink contacts skin or clothes, wash promptly.

Suitable for scrapbooking on dark papers, creating bold white lettering on posters, designing t-shirts or fabric accents, outlining illustrations on canvas, sign making, card making, and any project requiring high-contrast white marks on varied surfaces.

Pack includes 4 markers, each with a 3–19 mm mop-style tip and white water-based ink.

Choose Mop'R XXL when you need a broad to extra-wide white stroke with opaque coverage on light and dark surfaces. If you need a finer line or a slimmer tip for detail work, consider other POSCA white markers with thinner tips listed on Fepy (compare tip sizes, ink flow, and surface compatibility using the product pages).

First, ensure the cap is securely on and the marker is stored upright. Shake well and gently prime the nib on scrap material until ink starts to flow. If it remains dry, repeat priming a few times and check that the nib isn’t clogged or dried out due to prolonged cap removal.
