From The Book of Imaginary Beings, these small masks are affordable and still VERY special.
Each of the Wufniks has a number tattooed on his side. those numbers will count up from 1, and never be repeated. Each also has a scar of some sort across at least one eye, because being righteous enough to support the whole world does not come without pain.
From Borges: " There are on earth, and always were, thirty-six righteous men whose mission is to justify the world before God. They are the lamed Wufniks. They do not know each other and are very poor. If a man comes to the knowledge that he is a Lamed Wufnik, he immediately dies and somebody else, perhaps in another part of the world, takes his place. The Lamed Wufniks are, without knowing it, the secret pillars of the universe. Were it not for them, God would annihilate the whole of mankind. Unawares, they are our saviors."
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.
