The Ravensburger 3D puzzle uses unique "Easy Click" technology and high-quality plastic hinges that fit together and do not require gluing. The backs of the puzzles are numbered, allowing the model to be assembled by numbers and eyes. The impressive 3D model stays firmly together and can be disassembled and reassembled repeatedly. The set includes 216 plastic puzzle pieces and a base plate with a picture, on which you can attach the building for display. The palace is 12 cm high when folded, making it look like an acute decoration in your room or use an LED light as a night light, for example. Requires 3x AAA batteries (not included).
