This sketchbook with Munken Lynx graphic papers with a weight of 400 g\/m\u00b2 inside will take your sketching to a completely different level and make you experiment a little. Draw in it with charcoal, progress, Indian ink - the white sheets, which are a little harder, can withstand any technique! When you want to take out a sheet (and maybe frame it), just disconnect the opening rings - you don't have to tear anything and worry about your creation being ruined."}
