The ultimate nipple clamps?

Owner and i were away over the weekend and whilst out shopping we came across these in a cookware store;







Apparently they are table cloth weights for use when al fresco dining - how have we got through life so far without such little culinary essentials?! Owner, of course, immediately saw their true potential...and only £2.50 for 4! i can confirm that they are evil little things. They have a very powerful spring action and nasty little teeth, which, combined with the weights in the red balls, make for some great nipple clamps!
