i have OTR 160's that are like 5 years old, been used outside etc, and are still rocking the original nib with minimal damage. The eugene oregon buff crew had to paint over a throwie outline i did in a park bathroom 5 times before the stock paint that OTR puts in them stopped bleeding and showing through lmao. doesnt over saturate like the flowpen pump valve. i prefer this "paint marker"s valve with inks, over the heavier flowing flowpen valve, which seems to work better with thicker formulas (i like crisp not drippy though so.. matter of opinion)  5 of 5 Stars!

I should have read the reviews before putting thin ink in this bad boy. It leaked like a mother and I had to ditch it. If I have to put tape on a marker I feel like that's a con. Otr could probably improve the seal.  3 of 5 Stars!

Does this marker even need a review? If you don't already know about OTR valve action markers..they are some of the best if not the best valve action markers that you can purchase. Very durable nibs. Super easy to refill. If you use thin ink I would recommend throwing 1 turn around the threads of Plumber's tape so you're guaranteed not to leak at all.  5 of 5 Stars!
