The Staedtler Triplus Fineliner markers are slim and lightweight with a 0.3 mm superfine, metal-clad tip. The body is an ergonomic triangular shape designed for tireless writing (and preventing roll-aways). Each marker is also airplane-safe, featuring automatic pressure equalization that prevents leakage aboard an aircraft. A dry-safe feature allows several days of cap-off time without getting stuck with ink dryout. The water-based ink is acid-free and washes out of most fabrics.
This set includes 4 "basic" colors: Black, Blue, Green, and Red.
The case uses the same design that won Staedtler Japan a Good Design Award in 2007, granted by the Japan Industrial Design Promotion Organization. By simply bending the cover back and snapping it into place, you can turn the case into a propped-up stand for your markers.
