Product Information
Full details
The Staedtler Lumocolor Permanent Universal Pen is an ideal tool for professionals, students, and hobbyists who need a reliable, smudge-proof marking solution for overhead films, glass, plastic, and metal surfaces. Its standout benefit is the integrated Dry Safe technology, which prevents the tip from drying out even if the cap is left off for days, ensuring the pen is always ready for use. However, while the ink is permanent on most surfaces, users should note that the 0.6mm fine tip may require a lighter touch on rougher materials to prevent ink fraying.

FAQs
Are these pens permanent on all surfaces?
They are permanent on most non-porous surfaces such as glass, plastic, and metal. On some highly absorbent surfaces, the ink may sink in rather than dry on the surface.
Can I remove the ink if I make a mistake?
Since this is a permanent ink, it is not designed to be erasable. However, it can often be removed from non-porous surfaces like glass or smooth plastic using a cloth dampened with isopropyl alcohol.
How long can I leave the pen uncapped?
The Dry Safe technology allows the pens to be left uncapped for several days without drying out, though it is still best practice to cap them when not in use.
Is the ink acid-free?
Yes, the ink used in Lumocolor pens is generally considered safe for archival purposes, though it is primarily designed for industrial and marking applications.
Can these be used on skin?
No, these pens are not designed or tested for use on skin and should not be used as temporary tattoos or for body marking.
What is the tip width?
These specific pens feature a fine tip width of approximately 0.6mm.
Troubleshooting
Ink flow seems inconsistent or faint
Store the pen in a horizontal position for 30 minutes to allow ink to redistribute to the nib.
Ink does not adhere to a smooth surface
Clean the surface with isopropyl alcohol to remove fingerprints or oils, let it dry, and write again.
Pen tip feels dry despite Dry Safe claim
Cap the pen and store it tip-down overnight; this usually re-saturates the tip with ink.

Cons

Setup, Compatibility & Care
These pens do not require any specialized setup. To begin using them, simply remove the cap and touch the tip to your desired surface. To maximize the longevity of your markers, keep the following tips in mind:
- Surface Preparation: Ensure the surface is clean and free of oils or dust before marking to ensure optimal ink adhesion.
- Storage: Utilize the included stand-up box to keep the pens oriented horizontally or tip-down. This helps maintain consistent ink flow to the nib.
- Capping: While the Dry Safe technology allows for uncapped use, replacing the cap when not in use for extended periods will further extend the total life of the marker.
- Surface Compatibility: Test on a small, inconspicuous area if you are unsure about the permanency of the ink on specific plastics or coated materials.
