Recommended age: 14 years and up. Number of parts: 2246. Model size: 28.5 x 17.5 x 9.5 cm. Easy assembly without glue (pliers and a cutter/utility knife are recommended). Contents: environmentally friendly birch plywood, rubber bands, wax, wooden dowels, a clamp, toothpicks, sandpaper, and a pictorial assembly guide. Material: wood, rubber, wax. Tip: The model can be painted with wood colors (not included). However, it is important that the joints are not glued together with dried paint. Please note: Assembling requires some craftsmanship, as the delicate parts must be joined with controlled force from time to time. If handled too carelessly or roughly, individual parts can be irreparably damaged. As with other model building parts, it is essential to carefully review the assembly instructions, use less force, be patient, and proceed precisely. The environmentally friendly mechanical models, decorative puzzles, and toys made from renewable birch wood consist of plywood sheets. The respective sheets are created using laser cutting and are sometimes also decorated. The individual parts can be easily separated from the plywood sheets and assembled without the use of adhesives. The mechanical functions are realized with rubber bands (e.g., wind-up motors) or gears, bringing them to life with movement.
