Looking for the perfect project for hours of creative engineering? The UGears Safe puzzle kit comes with everything you need to build your own tabletop mechanical safe. The pieces are carefully cut to fit together precisely, so no glue is required. After the challenging assembly, this puzzle works as a fully functional safe, perfect for trinkets and small surprises. The pattern is designed after a real safe closet box but is made of real, fresh-smelling carved plywood with intricate gear systems that can be observed through strategic windows during operation. The mechanical combination safe kit comes ready to build with sheets of plywood containing 179 pieces. Glue or tools are not required, so the only other item you need is the instruction manual. This puzzle is ideal for experienced assemblers such as people over the age of 14 and those who genuinely enjoy the craftsmanship of spending 7 hours gently inserting tiny wooden pieces into carefully carved slots. The final result is a beautiful wooden piece that is ideal for display as well as for guarding small precious objects. Once completed, the safe can be locked and unlocked using a personal combination. At approximately 7 inches square (7.7 x 7.3 x 6.9 in), the box is ideal for all sorts of precious items. The gears can be viewed from the outside, so locksmith and safe enthusiasts can observe the mechanical elements as they lock and unlock.
