Tombow markers are a water based marker that have a brush tip on one end and a regular tip(not super fine) on the other. They come in a gazillion colors and because they are water based you can color right on your stamps with them,you can blend them easily with water or a blender,the brush tip writes like Brush style calligraphy. They last quite a long time too-I've had some of mine for 6-7 years.They can be hard to find-I plan to carry them in sets in my Shop in 08 but you might be able to find them on-line somewhere.they are pricey but worth it.Hope this helps!
