This is an elegant little mask; easy to get along with, but always alert. He hasn't -exactly- got his hackles up, but... well... maybe? At any rate, while I love the fanciest of the fancy masks, this is the kind I wear; interesting, but relatively simple. His nose is fine for eating a sit down dinner with a knife and fork, and works for most (but not all) drinking vessels. This is a poor choice of masks in which to eat a hoagie or a slice of pizza.
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. 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? He or she won't mind. They can hang flat against a wall, or sit on a shelf.
