Miniature Books feature tiny functional leather bindings, sometimes mounted on springs. Also, mini books with closures for travel, decoration, or wearing. For example, small refillable leather necklace books created as jewelry. Refillable necklace books contain loose folded pages for easy use. One page at a time easily removes from the tiny book. In contrast, miniature book necklaces can be fully bound, sewn together around cords. Blank acid-free pages or handmade paper fill the leatherbound miniature books.
