They say if you're always losing pens, buy a very expensive one and you'll never misplace it. If you feel the same way about sunglasses, we've got the shades for you.

That's Porsche Design's P´8951 sunglasses, which are freaking machined out of aluminum.

"The front and temples are milled with the utmost precision from a block of aluminium, giving the sunglasses a technical, masculine look."

"The front of the glasses is particularly ingenious. Its shape suggests two individual lenses, although it actually consists of a single shield."

"Porsche Design lettering is lasered on the temple. The bright aluminium in conjunction with the edges and bevels of the model also creates an impressive interplay between light and shadow."

They're only making 911 (of course) pairs, and they go for $1,200. You won't leave these on the café table.
