Ravensburger puzzles, the world's largest puzzle manufacturer with over 120 years of tradition, feature an anti-reflective finish. They are made from patented, strong cardboard with a soft backing. The graphics are printed on paper with a linen textured fiber that reduces light reflection and makes assembly easier, providing a sharper image regardless of puzzle size.
Thanks to the patented SoftClick technology, each Ravensburger piece has a unique shape and fits only in one place. The puzzle pieces vary in shape due to hand-cutting. Ravensburger puzzles are also resistant to bending.
