Works terrific on just about any surface but you'll get the best results the smoother they are. For whatever reason, I've never had great luck with these or the Shorty when using them on stickers. The new caps come with a little arm on the side to make taking it off easier if the cap starts to stick but I still wrap mine with athletic tape to get a better grip.
Some people complain that it's tricky to reuse these after they've been shelved for a while and that it requires re-breaking in the nib. To avoid this, I store them upside down (this works for any pigmented paint marker) and I've had no problems or ever had to worry about leaking.
I haven't purchased these directly from AP *yet* but I have racked tons of these from Blick art store . These are solid af for stickers . They are in fact permanent and opaque hence the name . You also if you're ballsy and refined enough to take apart and add your own ink and let me say it again INK like pilot in these if you're looking to take these to the street . out the box they are probably cool for insides but you're looking at Sharpie levels of ink ( they are slighty better than that but you get the point ) Thanks for reading my TED talk and stay up and stay safe
