Staedtler Lumocolor Whiteboard Marker - Bullet Tip - Pack of 4

The DRY SAFE ink allows the markers to be left uncapped for up to a few days without drying out, ensuring they are ready for use when needed.

Yes, these markers are refillable using the STAEDTLER refill station 488 51.

They can be dry-wiped from surfaces such as glass and porcelain without leaving a trace, provided they are wiped reasonably soon after application.

No, these are specifically designed as whiteboard markers and are intended to be dry-wiped. They are not permanent markers.

The writing line width is approximately 2.0 mm.

It is generally not recommended to use whiteboard markers on projector screens, as they can be abrasive or leave residue. Always check the screen manufacturer's guidelines.

Markers should be stored horizontally or vertically (cap up or down) in their stand-up box to maintain ink flow and prevent drying.

Ensure the cap was properly secured after the last use. If left uncapped for an extended period (beyond the DRY SAFE limit), the tip may need re-priming by drawing on a scrap surface or slightly moistening the tip with water.

Allow the ink a few extra seconds to dry completely before touching or erasing. Ensure you are using the marker on a compatible surface.

This can occur on older or heavily used whiteboards, or if ink is left on non-whiteboard surfaces (like glass/porcelain) for too long. Clean the whiteboard thoroughly with a dedicated whiteboard cleaner. For glass/porcelain, try cleaning with a damp cloth or appropriate cleaner immediately after erasing.

The 'Airplane-safe' feature should prevent this due to automatic pressure equalization. Ensure the cap is securely fastened before flying.
