Triplus Fineliners feature an ergonomic triangle shape for fatigue-free writing and drawing, and the silky, smooth barrel surface feels great to the touch. The .3mm superfine, metal clad tip gives an exceptionally precise line. Triplus pens are DRY SAFE; they can be left uncapped for days without drying up. The water-based ink washes out of most textiles. The 6-color neon set includes blue, pink, red, green, yellow and orange. The 10-color set includes yellow, magenta, red, orange, light green, green, light blue, blue, brown and black. The 20-color set includes the same colors as the set of 10, plus bordeaux, aqua, cyan, French green, olive green, violet, mauve, Van Dyke brown, gray and silver gray.
