I've just purchased a new set of Prismacolor brush tip markers. I purchased a set of 8 yesterday at Michaels at 40% off. So far, I am very pleased with them. On a journaled page with a coat of acrylic paint, there is no bleed through and they write quite well on the paint. On a composition journal page with no paint, the marker shows through slightly but does not actually bleed through. Even an ink pen will show through the paper a bit. The colors go on clear and are pleasing shades.
Now, here is what I like best. Usually I prefer using an 18/0 brush for line work, lettering, or pen and ink work because I just can't get the markers to work for me. But these are the closest I've ever found to the performance I want in brush tipped markers. I was so excited when I first found Micron brush tip pens. But when I press the brush tip to get a wider stroke, it does not recover to move to tiny stokes quickly enough to be effective. The Prismacolor brush tip marker does recover its shape quickly allowing for a stroke that goes from wide to tiny without lifting the marker. I have also tried Pitt brush tip markers. They do recover allowing a stroke to go from wide to tiny. But when I try to use the tip of the brush to create very small strokes, it tends to collapse making my stroke much larger than I wanted. The Prismacolor brush tip maintains its shape enough to allow tiny strokes too.
The Prismacolor brush tip markers are acid free, lightfast, permanent, water resistant, pigmented ink, and archival. My only real complaint was the lack of a pink in the set. I just wish I had a pink! LOL!
