Original Chartpak AD Marker - Tri-Nib & Blender, 6-Pack for Artists & Designers

This is a great blender- REALLY great for transfers- but I purchased another one solely to try it out as a blender for color pencils (I mainly use Irojitens, which have a harder lead than pencils like Prismacolor) and it did a so-so job. I think Gamsol and Prismacolor blenders do a smoother job. I have to try it out a few more times, but it seemed to sort of flatten the layers of color rather than blend them together.A few notes about the pen itself: it's POTENT. If you like the smell of xylene (think paint markers) you'll be in heaven with this pen because it REALLY smells. You need adequate ventilation, especially if you use a lot of it to cover a wide surface or keep the cap open. I kinda like the smell of xylene (which I know is odd) but this pen makes me turn on the fan and get frequent gulps of fresh air outside my studio.Second- I was kinda concerned about the nib because I tend to like a fine nib, but the chisel comes to a fine point at one end, and it's very firm and doesn't fray easily, so the pen can easily be used for detail work and for getting into tiny areas. I use it with a Ranger Nib holder and disposable nibs, so I touch that to the tip of the blender pen to get a little of the blending solution going and can change the nibs for warm and cool colors, so no mud and accidental color transfer.It's a powerful pen, great for blending Charpak markers and for transfers, but it's not the very best for color pencils.
