The "window" in Uni's Propus Window Double-Sided Markers refers to the design of the chisel tip, which features a window so you can see through to the other side of your marker tip so you never go over past where you meant to stop.
Each marker is double-sided, with the chisel tip on one end, and an ultra fine 0.4 mm tip, perfect for line work or writing, on the other. The Basic Color set comes with five bold, opaque colors, not suitable for highlighting. For softer highlighter colors, try Smoke, or Light.
