Language is a constantly changing thing, and I try to keep up with some branches, but fall behind on others. This, though, is a very stylish owl, regardless of whether I've used the words correctly or not. (also, I probably should've retaken these photos; the bags under my eyes are not the mask's fault; this one actually has larger, even more comfy eyes than normal. Those bags under my eyes are the fault of attempting to start photos first thing in the morning after being kept up all night by a new puppy. Mistakes were made.)
The wonder of a copper mask is in the strength and give of the material. Because it is so strong, the mask can be very thin- this makes it both very light, and makes it possible to fit as a second skin. These won't block your peripheral vision the way a leather. paper maiche, or plastic mask would. They can be very comfortably worn all day and night- no worries about sweat or rain causing them to soften and lose their shape. Rinse it with clean water at the end of the night before putting it away. All colours are created by carefully controlling heat and the metal's access to oxygen throughout the process and are both durable and archival. They can stand up to anything you throw at them. As for packing? Throw it in your bag. If you're checking the bag, maybe stuff a balled up pair of socks where your forehead would go. Easy.
Not planning to wear your mask? They won't mind. They can hang flat against a wall, or sit on a shelf.
