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

I bought these pens a while ago but I have been using them until recently, they can make excellent intense dark lines. I've noticed that my 0.4 and my 0.80 (for some reason) don't differ in the thickness of the lines they should have, the smaller tips also make great thin lines. They require extra care when cleaning and I would suggest doing this as soon as you are no longer using them as all nibs are prone to clogging, small sizes mostly. I've used these pens twice, the first time I washed them as soon as I was done with the liquid cleaner that Kho-I-Noor sells. The second time I decided to wait and see how long the ink can be stored before it becomes a problem, large nibs can last about a day before the ink runs out, but small nibs, mostly the smallest ones, can't be stored longer than 6 Hours of stored ink in them before they bleed out. I would say this ink liner gives great results and I would advise potential buyers to invest in them, just be aware that they require a good cleaning. Overall they work great for me, you need some ink to last and the quality of the ink that comes with this set is great too.
