The Ravensburger 3D puzzle night light Batman combines puzzle fun with a practical light source for the children's room. The 72 curved plastic puzzle pieces can be assembled into a stable sphere without any glue thanks to Easyclick Technology. The pieces are numbered on the back, which makes sorting and building easier. After assembly, the 13-centimetre diameter puzzle ball is placed on the included LED light base. A simple clap of the hands is enough to turn the night light on or off, making the finished model a functional decorative item for all Batman fans.
