Profi-Marker Set

This Profi Marker Set is a must - have for working with granite, marble, engineered stone, quartz, and all natural stones. It includes 2 blue refill pens and 17 markers (1 box of 5 Red markers with 1 pre - installed, 1 box of 5 Black Graphite markers with 1 pre - installed, and 1 box of 5 Yellow markers). Made in Germany, these high - quality pens are far superior to China markers or grease pens as they don't leave a grease film. They're durable enough to withstand fabrication processes without washing off and can write through standing water. To use, simply push the back of the pen, and the front opens to let you adjust the omnichrome wax marker to the desired length. Loading a new marker is a breeze; just push the back, open the 'mouth', insert the new marker, and you're good to go in 2 seconds. Use yellow or red on medium to dark stones and black (gray) on light - colored ones.

Using the Profi Marker Set is easy. When you want to start marking, push the back of the pen. The front part will open, and you can slide the omnichrome wax marker out to the length you need. If you run out of a marker, push the back again to open the 'mouth' of the pen. Then insert a new marker, and you're ready to continue in just 2 seconds. For best results, use the yellow or red markers on medium to dark - colored stones and the black (gray) ones on light - colored stones. These markers are durable, but still handle them with care. Don't expose them to extreme heat or moisture as it might affect their performance. When not in use, store the pens in a cool, dry place. And if you want to keep them working well for a long time, try not to force the markers out too far as it could break them.
