Jumbo Markers for Large-Scale Projects

The BIGTHUMB set includes three black permanent markers built for artists, crafters and sign makers who need broad coverage on posters, canvas, wood, rock, glass and ceramic. Water-based acrylic ink is non-toxic, acid-free, low-odour and conforms to ASTM D-4236 and EN-71 safety standards. Each marker delivers waterproof results once dry.

Pump-Action Design with 3-in-1 Nib

A pump-action valve gives direct ink control without shaking, while the reversible felt tip switches between fine, medium and 15 mm jumbo widths simply by changing the grip angle. The wide tip lays down heavy colour fast, and the finer edges handle outlines or detail work without swapping tools. Quick-dry formula reduces smudging on non-porous surfaces.

Replaces Multiple Single-Width Pens

One marker covers the work of separate fine-liner, broad-tip and jumbo pens, cutting clutter for muralists, teachers and DIY decorators. The jump is worth it when a project demands both bold backgrounds and crisp edges on the same surface. Buyers who need metallic, fluorescent or white opaque ink will need a different formulation.

Questions about this item

How wide a line can the 15mm tip lay down in a single stroke?

The jumbo tip produces a solid 15mm line, and rotating the barrel lets you switch between fine, medium and jumbo widths without changing nibs.

Will the water-based acrylic ink smell or bleed through paper during long sessions?

The ink is non-toxic, acid-free and odourless with no leakage, and it becomes waterproof once dry, so extended use stays clean and low-odour.

Which surfaces are confirmed ready to use straight from the pack?

Poster board, sign material, canvas, wood, paper, rock, glass and ceramic all accept the ink without priming.
