This month is all about acrylic ink! Our Premium Box features Holbein acrylic ink in naphthol red, 30ml. This highly versatile ink is super pigmented with a very low viscosity. Use it with the 3/8" Dynasty dagger brush that was also included in this month's box, or try using it with a dip pen, a water brush, or a refillable marker. To provide a full primary color set, we also included two 12ml Speedball calligraphy inks in primrose yellow and indigo blue. These inks are waterproof when dry, acid-free, and very lightfast. We also included a Caran d'Ache 4h pencil to lightly sketch your drawings before going in with ink, as well as a Staedtler pigment liner 0.3 2mm in black. This calligraphy pen is waterproof and lightfast and allows for variance in line weight. Our surface in this month's box is a custom Magnani cotton pad. This SketchBox exclusive 10 sheet, 104lb cold-pressed paper is perfect for wet media. Finally, we included a SketchBox Signature 6 well palette for mixing the perfect colors.
