Pen-Touch Medium UV blue
This Pen-Touch has a medium nib size (2.0 mm line width) and UV blue ink that is invisible in broad daylight but will light up vividly under blacklight! This pen is perfect to add invisible name tags to your belongings or special effects to your artworks, but also fun to write secret messages with or to add some ‘magic’ in crafts and children’s games.
Pen-Touch writes on a wide variety of surfaces including cardstock, plastic, wood, glass, porcelain, paper and metal.
Before use, shake with the cap on to get the ink flowing and mix the colour. Depress the tip in an upright position to release any internal pressure. The ink will flow from the chamber directly to the tip of the marker.
Pen-Touch ink is chemically stable, waterproof and applicable to many surfaces. Whether the mark is permanent or not depends on the surface and the conditions applied to the mark (washing, scrubbing, chemicals, heat, cold, etc.).
