World Dimmers

Okay, polarizing filters for the literal minded. Each filter is a 20 mm dia x 2 mm think piece of glass with a couple of tiny slots in the edge. Each has 20% transmission by itself, which may not sound like much, but is about what you get through decent sunglasses. We are selling a pair so you can do experiments on transmission as you rotate one against the other to reduce the light getting through virtually to nothing. Or you can make some very cool granny sun glasses if that turns you on. The big guys get upwards of $7.00 per filter for these dudes!! Isn't surplus cool??
