PostBox is a monthly stationery box! PostBox is a card box. Each PostBox subscription comes with a monthly, limited-edition delivery of beautiful handcrafted artisanal greeting cards and postcards created by artists around the globe. Each month, your PostBox card box is filled with four greeting cards, one postcard, postage, and a fun artsy doodad such as a pen, pencil, or knick-knack gadget based on a theme. The value of the products in your subscription box will always be what you pay for each month, sometimes more. There may be a surprise bonus gift some months, so you don’t want to miss a box!
