Benefits

The extra ink amount means fewer refills and longer creative sessions, offering clear value for money compared with thinner markers. Colours are bright and easy to remove from glass, blackboards and many non porous surfaces using a damp cloth, which helps when updating menus or lesson boards. They are water based, non toxic and xylene free, so they suit classroom and family use with minimal odour. A useful caveat, according to the manufacturer, is to avoid porous surfaces as these will absorb the ink and may leave ghosting.

Best use cases

Teachers, shopkeepers and crafters will appreciate the versatility of the rectangular nib for quick large lettering or precise accents. It’s a practical choice for writing on café windows, car glass for events, classroom boards, LED displays and DIY projects where vibrant wet erase colour is needed. Window Pens - 15mm Jumbo suits repeated use in busy settings and classroom routines.

Getting the most from it

Keep the caps on when not in use and test a small hidden area before writing to check surface compatibility. You’ll like it if you need long lasting neon ink for bold signage and temporary displays, and it makes sense if ease of erase and high visibility are priorities. Bear in mind that porous materials will not wipe clean and may retain marks. 😊 ✨
