These little fellas are great! I used to pick these up down at my craft shop all the time. You can write on practically anything but do yourself a favor and save it for smoother surfaces cause there is not a whole lotta paint in them. I love all types of streaks and these ones I have found to be just as good as any other, with the exception of less paint. The only negative feedback I could think of is that it did kind of get a very weathered look after not being out for too long, but in my opinion I actually love the weathered look it has, it gives your tag some character. Oh and one final thing they definitely do not last as long as an AP streak would but I was still very surprised at how long it lasted. I was really pleased with this marker and I think that everyone who gets it will share my thoughts on it
Sweet for small tags. If the nib breaks down on you, just take the nib out, flip it, and put it back in. Simple. You can even put a decocolor nib on it. Decent marker, nice to carry around even if you don't expect to do anything. You never know.
