The Uni Posca PC-8K marker has a broad 8mm chisel tip nib.
Use the pens on practically any surface, including metal, wood, fabric, plastic, canvas, etc. They’re even suitable to use on paper and card, as they don’t bleed.
The ink can be wiped off glass easily, making the pens wonderful for creating temporary signs and window art. You can even create your own permanent designs on terracotta and glass by baking in the oven, or on clothing and other fabric by ironing on the reverse.
