Review on Black Sakura Pigma Micron 05 Pigment Fineliners (Pack of 3) - 0.45mm Point Size by Doris Tran

I bought this pen to sign and date the back of fine art photographs for sale. I can't tell you how many photos were ruined because that ink never dried. An hour later, when I went to put the photos into the acid-free sleeves, the back of one of them was smeared with ink. Then after a few hours I checked the rest and just touched my signature and the ink was all over it. I've never seen that in a pen. Prints costing more than a few thousand dollars were worthless and had to be reprinted. I was so pissed that I bought this pen for one reason: to sign artistic photographs. Useless. Out of curiosity, I used Canon Pro Luster paper and signed the back of the paper.
