This Shuttle Art alcohol marker set includes 51 pastel permanent markers featuring 50 pastel shades and one colorless blender. Each marker has a dual tip design with a 7mm chisel tip for coverage and a 4mm brush tip for varied strokes. The ink is acid-free, non-toxic, and designed to blend and layer without streaking. The markers feature an ergonomic triangular barrel to prevent rolling and provide a comfortable grip. The set comes with a magnetic marker box that converts into a triangle holder and a transparent sheet for backing or color testing. These markers are suitable for journals, notes, and sketchbooks.
