Those who know
me, for example, will know I have little interest in
physical exercise. But I bought a mat intended for such activities
because it was a suitable material for lininng a carrying case for a
piece of photographic equipment.

Be careful.
CORRECTION: the most expensive item destroyed was a Leica 180mm
Tele-Elmarit f2.8 lens. It had been mint condition before he put it in
the case. Not much damage to the glass, but it destroyed and pitted the
finish of the rest of the lens, removing all collector value.
