Uni Propus Window Double-Sided Highlighter - Smoke Gray - 2020 New Color
The highlighter tip with a window, which is a feature of the "Propus Window" series, is used, and characters can be seen while drawing a line, so you can mark clearly without sticking out where you want to draw a line.
The "Propus Window" series has been developed as a twin type for both bold and thin letters for some time, but Uni found that there is a need to write letters on the thin side. Therefore, by changing the conventional fine character (0.6 mm) tip to a thinner, finer (0.4 mm) plastic tip, which helps not only for underline applications but also for writing applications. Now you can use it as a color pen for your journal.
Tips size: 4 mm windowed chisel tip and 0.4 mm extra-fine tip
