This month is all about watercolor markers! Our September Premium box features two Akashiya Sai watercolor brush pens in rose red and pink, and an Akashiya Sai ThinLINE pen in pine green. We've also included two different dual-ended watercolor markers: a Winsor & Newton ProMarker in burnt umber, and a Faber-Castell Watercolor Marker in indian red. For details and outlining, we've included a Pentel Microbrush in black as well as a KingArt Inkline chisel-tipped fineliner in brown. To add water to your art, we included a SketchBox Signature mop brush. This 3/8" fluffy brush is great for creating large swaths of color and can hold a lot of pigment! Our surface in this month's box is a custom Hahnemuhle Harmony pad. This pad is 300 GSM, 4x9" and includes 12 sheets.
