The decorative tin, with its picture frame lid has 12 cards. Size: 4x6 Paper can be made from any plant fiber, not just trees. We use tree-free alternatives like Kenaf whenever possible. This fibrous plant grows 15 feet in just five months, uses no harmful chemicals in processing and is fully recyclable. Kenaf is grown here in North America - bringing income to farmers and preserving our forests. We continue to strive toward the use of 100% tree-free paper. Unfortunately, it is a struggle to find it in the quantity and the quality we need. Every card purchase helps us to build a more consistent supply of tree-free paper, ultimately helping our forests to stay tree-full.
