Hultafors HPM Permanent Marker Set - 4 Piece

These markers adhere to almost any material, including paper, cardboard, plastic, metal, wood, glass, and fabric.

The product description does not specify refillable cartridges. These are designed as disposable markers.

With the cap securely replaced after each use and stored properly, the ink should last for a considerable time. However, alcohol-based inks do have a finite lifespan once exposed to air.

While the ink is permanent and adheres well, prolonged exposure to harsh weather conditions (UV radiation, extreme temperatures, moisture) may affect the longevity and vibrancy of the marks over time.

The alcohol-based ink is generally water-resistant once fully dry, but submersion in water may cause some fading or smearing.

It indicates that the markers are produced using environmentally conscious practices and that the packaging is made from recycled cardboard paper.

Yes, the markers can be used on fabric, but for the most permanent results, especially after washing, heat-setting the ink with an iron (following fabric care instructions) may be beneficial, though not explicitly detailed in the product info.

Ensure the cap was securely replaced after the last use. If the tip is dry, try pressing the tip firmly onto a scrap surface for a few seconds or gently scribble on a damp cloth. Store markers tip-down.

Allow a few extra seconds for the alcohol-based ink to dry, especially on non-porous surfaces. Ensure the surface is clean and dry before marking.

Check if the marker has been stored correctly. If the marker has been stored for a very long time or exposed to heat, the ink vibrancy might be reduced. Try the tip-pressing technique mentioned above.
