Always have your sketchbook with you! The medium wallet is roughly 4x4.5 inches. The square format is great for posting to Instagram :-) It comes in a gift box with a short 2B drawing pencil, a page clip, and one 3.5"x3.5" blank white paper replaceable sketchbook with 60 pages. The wallet has 5 RFID blocking card pockets and a money pocket across the top like a traditional wallet. It's the perfect pocket-sized sketchbook for sketching on the go.
