Several days ago I received the tip to use the rubber washer of swing top beer bottles (here's a picture of such a bottle: http://www.brauen.de/images/product_images/original_images/buegelverschlussflasche_1_liter_braun.jpg )
as a guitar strap stop.

After emptying many beers and possibly establishing a strap stop mail order company somebody has had a nice idea to reuse the bottles:

Enjoy.
