I would have to say that is the number one tool in japan that came to the usa that is better then sliced cheese O_O. I really love the work you can do in it and all the kinds of style you get to use is more then enough to make a ton of artwork with only one pencil!
Who here has em?! and what do you think of them?
I don't have any personally, but I have used them. 
They rock forever. ;D
I think I've heard of these before. Whats so special about them?
They really color well, and allow you to blend colors together without looking rough. My friend, Keasha, uses them on her anime like drawings. ;D
Sounds cool. Perhaps I should get a set of those...
Yeah, they rock. I color the best with them. ^^ There's normal pencil ones too that are really smooth and stuff. It's great. ;D
Personally when it comes to it, I like Prisma (is that's what you meant then yeah I like them)
However I perfer to use mediums inported stright from japan, happily I have a art store not too far away that gets import mediums
You're lucky that someone else them near you. ^^ I just borrow them from my friend.
Yeah, we have really cool little shops around me. Plus, we have many artists and hold awesome art shows. I'm still trying to get some of my friends to put there stuff in galleries.
Really? That sounds great! You and your friends must be really good artists. ^^ But what are those other pencils you mentioned? Prisma? @_@
