GRAFMETAL highlighter ink will allow you to refill your used highlighters instead of buying them again. The offer is for a 30 ml bottle of ink. One bottle can be enough for up to 30 refills. On request, it is possible to order ink in large quantities at a lower price. Available inks in YELLOW and GREEN colors.
Refilling is possible for both unscrewable, refillable highlighters and highlighters that cannot be opened or have a damaged writing part.
The ink comes with a highlighter dropper, so all you have to do is put the bottle's outlet to the highlighter and then tilt it. Dispensing 20 drops per highlighter will allow you to refill about 30 from a single bottle!
The color intensity is the same as that of brand-new highlighters from recognized brands, as shown next: one of the lines was made with GRAFMETAL ink, and the other 2 with branded highlighters.
You can, of course, use the ink by using other tools, such as cotton balls or brushes.
The ink is characterized by high intensity glowing under UV light.
The intensity of the luminescence of the paper so painted is so high that you can see the areas circled on the other side of a paper sheet!
One drop dissolved in 250 ml of water gives a very intense glow. Thus, the ink can also be used to monitor leaks or diffusion processes.
On special request we can produce bigger quantities of ink in different colours.
The ink is a water-based material, not intended for consumption. Refill should be carried out in areas protected from ink staining. Stains on the skin can be rinsed off with water. Ink is not a hazardous material. The ink is designed for paper, it may not work well on other substrates.
