Our very first batch of DrawnBy: Colouring Stickers is printed on matte-finished paper so you have much more options in terms of colouring! You may use anything from colour pencils, to crayons, to gel pens, to of course, our DrawnBy: Markers themselves to colour in the decals. Do note that inky pens may smudge so you should allow the ink to dry a little before peeling the DrawnBy: Colouring Stickers off to to paste :)DrawnBy: Markers and Water Colour Pencils are actually erasable off this first batch of Colour Pencils - it was a pleasant surprise because we didn't expect them to be reusable too! Do note that this matte-coating will be REMOVED in further runs of DrawnBy: Stickers.Care FAQ
