I bought Copic markers for the first time! Sketching Gray set. They are great but damned expensive.
Here's just some of the things that these markers do:
Come in a wide variety of colors
Can be refilled so you don't have to buy more
Won't make the paper 'pill' into little balls when you saturate the paper (of course, that depends on the kind of paper..)
Make your pictures look TOTALLY BADASS
Can be used on things besides paper
Give you superpowers
Protect you from vampires
Is it any wonder why these markers are so awesome? Of course, I had to sell my kidney to buy them, but who gives a crap? I'm going to enjoy my Edward Cullen repellent.
