There's an antelope at the Field Museum who has, just, the BEST horns. They curve slowly and elegantly and they lend him height and elegance and glamour. He's just a pretty fellow. Anyway, that's a sable (there is also a weasel who is called a sable, and they're great, too, but they are different. No horns.).
The slight weight of this mask, as with all my horned masks, is balanced through the horns; your mask will rest on your head lightly, like a cap, with your nose only acting as an anchor point. This one's horns end in a tight spiral for safety, unlike his namesake, who looks, frankly, a little stabby.
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.
