Our journals feature a 6-ring binder that fits standard A5 or A6 stationary or 2-ring pocketbook size. We sell refills for all three sizes, as well. Luxe journals fit standard A5, the Traveler journals are A6 and our Everyday Carry size fits your standard 3 x 5 index card. Each journal includes 120 sheets (240 pages) of 100gsm lined paper so that ink does not easily bleed through. Additionally, for our artists we carry 180gsm blank art paper. We provide a lifetime guarantee on all hardware.
