In the sense of being a metal case providing a barrier from the elements, this would prevent water (from rain/ snow) from getting into your case, however the item does not specifically have heat-resistant elements to it. This means that if you take this out into the sun, the items would be more protected than they would just being loose (say stored in a pocket or purse), but as a makeup artist I try and avoid leaving my case in direct sunlight for super extended periods of time.
Try storing the case in the shade if you are taking the item with you direct sunlight, but when this is closed water would not get into the case. This would also be great for travel (store with your checked luggage) and is able to withstand the type of heat from storage on a plane.
