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

I've been using Ink Liner for about 16 years now and with good reason. If you want to be in control of your ink choices, this is the way to go. Proper handling and regular cleaning (weekly or bi-weekly depending on the ink) will prevent clogging and leakage. The lines produced are far superior to all disposable multilayer liners (read: microns). This is the second set of 7 pens I've bought and this one was with Ultradraw ink (my other was with Universal, about 16 years old). return). Ultradraw is one of my favorite illustration inks and is also ideal for beginners due to the long open time of the ink. This is definitely a plus point in my book. A NOTICE. Do not travel while the ink cartridges are filled with ink. They just beg for leaks and then clog. Don't shake them or be rough with them. This is a precision tool and should be treated as such. Treat them right and they will treat you right for a long time.
