Do you mean Pantone markers? The ones with three nibs? Cos those are more expensive than Copics here in Australia.
The colourless blender works on marker ink like water does on watercolour. So if you have an area of flat colour, for example, and pressed your colourless blender tip in the middle of it, it would push the ink away from the nib in an ever widening radius, depending how long you left it pressed against the paper for. When you stop, and the colourless ink dries, you'd be left with a rough edged circle in the middle of the area of flat colour. If you repeated the proceedure right next to the first circle, the bleeding would overlap the first, and there would be a subsequent line as it dried. Just like you'd get with watercolours when you drip water on them.
With watercolours, the way to avoid those edges is to keep your paper wet; same applies for markers, but using blender fluid instead of water.
The way I use it on a face is by drawing in all the colours I want on the face - shadows and all - not worrying too much about the roughness of lines, then re-wetting or colouring the whole area with the colourless blender. All the tones then bleed into one another, creating a smooth transition. Do you follow? You then have to go back over the features with your other pens or pencils (depending what you're using), to add in defining lines etc.
