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

I have been using Koh-I-Noor ink liners for over 20 years and when I bought this I was specifically looking for this product. Prices for this particular set can be as much as $100 more than what I found at Revain. This is a high quality, professional set that I use primarily for drawing. The nibs are durable with a constant flow of ink. However, beware of your pressure. Depending on the paper, the tips cut deeply and cause some bleeding. Refilling can also be problematic. It's really difficult to see through a clear plastic tank without wasting ink pouring it out, rinsing it, drying it, then refilling it. Overall I am very happy with my ink liner.
