The Muses inspire us when we least expect it. So I designed this sketchbook with that in mind as it's wrapped in inspiration from my muses. It's 5 1/4" x 8 1/4" size is perfect for your bag with 144 pages of 70lb. bright white sulfate paper and a velvet-feel cover that resists moisture and can take a beating! I hope these sketchbooks travel everywhere with you as you record your world and create!
