got two of these: bleed thru red and violet. the violet is hella dope! no streaks, no nothin. the only problem, based on my own usage, is that it's easily buffed with chemical solvents. it wipes off with little problem, but leaves a little purpleish smear behind.
the bleed thru red is tight too. i got a TINY bit of streaking with it, but barely enough to be a problem. it's called bleed thru because it is. the only problem is that it fades in direct sunlight after a while. i caught a tag maybe 4 weeks ago, and it's faded to pink. it's dye based im pretty sure, not pigment based so it won't show up on black surfaces.
the nib is also very durable. i've had this marker for a few months now, and haven't had to replace em.
i recently got the white, blue, orange and green. all colors are good and so far they havent faded in the sun. i did a white/blue split, and its ok. i would recommend a yellow/blue split instead because the blue kinda overpowers the white and its hard to see the white. but these arent buff proof. all you need to remove it is some rubbing alcohol
