Harry,
I believe that you are referring to a product called "Microbrushes" I have them on my workbench, and buy them by the "100" size via MicroMark. I use them all of the time, and as you stated, they come in a variety of sizes. I am planning on picking up some non-acetone nail polish remover to use them for removing tampo markings.
