Ravensburger's 3D puzzle uses unique "Easy Click" technology and high-quality plastic hinged pieces that fit together seamlessly and do not require gluing. The backs of the puzzle pieces are numbered, allowing you to assemble the model both by numbers and by eye. The effective 3D model stays firmly together and can be disassembled and reassembled repeatedly. The set contains 216 plastic puzzle pieces and a base plate with a picture on which you can attach the building to display. When assembled, the size of the building is approx. 21.5*11.5*27.5 cm.
