These ARE exactly the same as the K-71's, but in my opinion, better. The black NEVER needs to be shaken to produce an even flow and opaque ink, the nib is hella solid so the handstyle is very sharp.
yo this marker is dope i got it today but after like 5 tags the nib ripped off!!!! i was so mad its still full of paint i think i might try glueing it back on but idk if you get this marker be careful of what you write on.
