Review on 🖋️ Koh-I-Noor 3165SP7P KIN3165-SP-7 Radiograph Technical Pen Set with Assorted Nibs - Multicolor by Morgan Gilmore

These pens save lives. I do fairly large screenprints and each print costs about $15-$30. I've had them for about a year now and I still haven't had to buy replacement inks. They're great for dot printing - the fact that the nib is designed to sink into the nib means you no longer have to crush your marker nibs before you run out of ink. Also, I found this to be the only pen that dries to Clear-Lay. BUT DON'T FORGET TO CLEAN THEM. You can use the small gears that come with them to take them apart (down to the spring for example) and clean them with water, Kor-i-Noor cleaning solution or rubbing alcohol (but wash off the rubbing alcohol quickly) . may cause rust on metal). hot device for a long time, just empty their ink tanks and clean them beforehand. trust me on that. With relatively minimal but regular maintenance, these will be the only pens you'll ever need.
