I ordered this case as a lockable, portable, protective case for a faire arm I recently perchased and all of its gadgets and tools. The case is awesome. I do kind of wish that there was an option for the solid layers of foam but the cubed foam layers work well. for info the foam is in. 5 X. 5 X 2 inch sections so cubed is not quite accurate, and also realize that there is a solid foam ''frame'' around each layer that is about 1'' all the way around and take that into consideration when looking at the dimensions. As far as the construction of the case, I have used many pelican products for many different reasons and have never had any issues with them and this case is no exception. It is water and air sealed(except for the automatic pressure valve for when there is a significant change in air pressure i. e. Elevation) and is made from a very durrable material with good craftsmanship. I would recomend these cases to anyone wishing to protect valuable items from the elements and the abuse of travel or shipping.
