This sketchbook contains 30 sheets of our awesome, unique paper which is a hybrid of bleedproof marker paper and Bristol board - making this the perfect marker pen pal! At 250gsm, this superior acid free smooth 'bright white' hybrid paper is versatile and suitable for all markers. It features a twin wire bound edge which allows the book to lie flat and makes page turning a breeze. In addition to the high quality FSC certified paper, we've added sturdy, black, hardback covers front and back with a 'soft touch' laminated finish making them both durable and wipe clean. Artgecko sketchbooks are available in a range of species - each with their own, unique, chirpy features (both inside and out). You'll be happy to know all our Artgecko sketchbooks are British made using only the highest quality materials from climate friendly, sustainable sources.
