This is a nice little, must have marker. I use it for outlining sketches with High Solid or CoversAll. I always have a few of these empties around in case I need to drop some different colors on the fly. Good quality, super reliable and nibs are easily replaceable. TIf necessary, the nib is can be washed with water (acrylic) or denatured alcohol (my solvent of choice for ink).
Pack is a hell of a deal. Purchased this pack 3 times so far. Other then the fact the price is awesome that's about as far as it goes. They stuff your pack with hella black and hella white literally have 30 plus cans of just black/white after buying this pack 3 times.
These things are dope as hell, perfect for bringing to court, the airport, a funeral, or anywhere you know you won't be smashing tuff, but still want the option. Hell, I might even keep one hooped for the next time I get locked up - they are that small. A single fill goes a lot farther than you would expect.
As for the nib being tight as hell, if you finesse the insertion/removal you should be all right. But since my homies are lazy, I tried out running a dremel with a sandpaper attachment in the opening of the body. This eases it up a bit, but still keeps a solid seal. Haven't had any problems so far so I think I am going to do this to the rest of em.
Bought a 20 pack to fill with my home brew paint/ink (it works great with both) and give out to the homies in the crew for antichristmas. When you buy 20 you get them for less than a dollar!
These dope little nibs also work on the Grog squeezer 05 and the Kobra nano mop, they also fit perfectly into a bunch of random things. Those zig zag vape liquid refills work great for a easily made mini mop. You gotta drill out the cap so the nib fits or find another cap, but that is easy enough.
