Bests & Worsts Reviews from Amazon

as an illustration student i go through a LOT of pens. so i've tried to buy and use pretty much every major brand of ink pen to see which is the best, and hands down i've never used a pen better than these! they are truly waterproof, dry quickly, are rich in pigment, never bleed through the page, won't lift if erased over, and have a flat matte texture when dried (as opposed to say, sharpies, that have kind of an oil-spill shine). the only thing i dislike about them is that they kind of gum up if you try to use them over colored pencil, but that could just be because i use wax-based prismacolors. in my several years of using these pens i've never had any problems with ink leaking. if you're looking for a great quality, versatile pen set these are DEFINITELY worth the purchase especially at amazon's price!!
