This expansive 1000-piece Ravensburger jigsaw from the "Nature Edition" series has a rare sulfuric acid lake at Mount Ijen in Java as its backdrop. With the premium puzzles from Ravensburger, enjoy unrivalled puzzle entertainment. Thanks to the handcrafted punching knives, the one-of-a-kind puzzle pieces fit together properly, and there is an unmatched variety of shapes. Their puzzles use a linen finish print to reduce glare on the puzzle image and are composed of sturdy premium-grade cardboard. For 150 years, Ravensburger has produced puzzles and games, and they take great delight in offering the best selection and best quality. Each piece is precisely imprinted, and a soft "click" can be heard when one is placed inside the other. To ensure the greatest possible accuracy and variation of the puzzle parts, the puzzles are created using special punching templates and equipment that are handcrafted with watchmaker precision.
