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.

Love this product
This product has been the best. A small amount goes a very long way. You don’t feel greasy after just moisturized. To me, it doesn’t really smell like anything. it’s not overpowering or noticeable after it’s rubbed in. I definitely will recommend and continue to buy.

I tan pretty easily. I tan outside during the summer time ...
I tan pretty easily. I tan outside during the summer time and the winter i go to a nearby tanning salon to keep my tan going. I dont know why certain people say that this product smes like coffee, but it does not smell like coffee to me. It smells like paradise on beach. like thr tropics. and I love the smell. I also love the fact that within 1 use of this , i got a darker deeper tan . took me to the next level. noticed a huge differrence in my tan. I love this tanning lotion. and as far as people saying that its too oily, well, it is oily, but that honestly doesnt bother me one bit. this is by far the best tanning lotion i have ever bought. if u want to get a good tan thats natural. this is the stuff to get.

Best lotion for sunburned skin
After a vacation in Hawaii, I thought I’d never get to have this lotion again. I saved the bottle from 15 years ago, just as a memory. On a whim, I looked on amazon and here is was!! The best after sun lotion ever!!! Sun burns don’t hurt on the second day. Keeps burned skin moist and flake free. Peeling is minimal if you use the lotion daily. I still use it, even though my summer tan has been established. Smells like my vacation all over again!
