02551: GEAR,ANTIBACKLASH,SPUR.
A real feast for lovers of creative toys. Origami 3D are unique sets that will allow you to create the most beautiful 3D paper sculptures you have ever seen. All this thanks to patented modules, very detailed instructions and step-by-step instructional videos showing how to assemble the selected model.
The set includes ready-made cut shapes, with a clearly marked bend line, even suggesting the direction in which we should do it. In three simple movements, we can make a basic module that will be used to create a masterpiece. All modules are assembled identically and then joined together without the use of glue to form a figurine.
