⚡ At a Glance
- • Marking Quality: Opaque white coverage from 28 gram ink per marker and a 15mm nib for strong, readable strokes
- • Best for: Teachers, artists and small businesses needing bold window and board signage
- • Not ideal for: Porous surfaces such as paper or unsealed wood where ink will absorb and ghost
15mm rectangular nib combined with 28g of white ink produces bold lettering and fills. Designed for use on non-porous surfaces such as glass and whiteboards.
High-visibility signage – thanks to 28 gram ink per marker
Each marker contains 28 gram of white, water-based ink that lays down dense, opaque strokes ideal for filling and outlining. The larger ink quantity supports longer runs before the pen feels depleted.
Bold headings and filled lettering remain legible from a distance, so menus and adverts stand out. Less frequent rework is needed during a busy session.
Versatile line widths – with a 3-in-1 rectangular nib
The rectangular nib serves three functions: the wide edge for broad strokes, the flat face for bold lines and the corner for thin, fine details. The single nib design switches between styles by changing angle and pressure.
Headlines, subheadings and delicate details can be created without changing pens, speeding up sign-writing and decorative work.
Easy cleaning and temporary signage – thanks to water-based wet-erase ink
Water-based ink performs as a wet-erase formula on non-porous surfaces and can be removed with a wet cloth; porous surfaces will absorb pigment and may leave ghosting. Always test a small hidden area first.
Quick updates to menus, classroom displays and seasonal signage are straightforward, with marks removed without harsh solvents.
