As a bonus, each puzzle set includes complimentary white puzzle frame mats. Upon completion, the puzzle measures 23.2 x 17.6 inches. Pintoo jigsaw puzzles employ snug interlock and UV LED printing technologies that ensure firm interlocking of uniquely shaped puzzle pieces without the need for glue, guaranteeing a satisfying puzzle experience. The UV LED printing technique ensures that the ink does not penetrate the puzzle surface, resulting in sharper, more vivid colors and detailed visual presentations. Pintoo's jigsaw puzzles feature high-density plastic pieces that are smaller and sturdier than traditional cardboard puzzles, allowing for a more compact finish that takes up less table space. Additionally, completed puzzles can be stored vertically, similar to a book, making for a space-saving storage solution. Pintoo offers custom-made frames designed specifically for our no-glue-required puzzles. With our DIY frames and snug interlock technology, displaying your completed puzzles has never been more effortless. Please visit the Pintoo Storefront for additional information.
