Sometimes. Sometimes we give in to temptation- even knowing the thing we're about to do is silly, and unnecessary, and maybe even downright stupid. We do it anyway.
Ahmed is one of a set of quadruplets. They're all cut out of one big tea tin. Cutting them out cleanly- and then cleaning them up to a comfortable edge- took far more time than you imagine, and all four of them ought to cost far more than they do. But the metal that teatins are made of is thin, and I'm not confident in their long term duribility. Consider their low price to be my payment for you writing to me in four years, and then, if you remember, again in twenty, and if we're both still around, again in fifty years, and telling me how they hold up. I'm curious.
They are still flexible, and comfy- but I wouldn't toss one in my luggage without packing it up pretty carefully. They're even lighter than normal, though, so there's that.
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.
