I stuff my breasts full of lead, in order to keep the cockroaches away. It's a very simple procedure, taking about 2 minutes, 3 if you're slow. However, it's rather expensive, costing nearly 500 dollars a breast. And of course, you can't just stuff one and not the other!
But you get your moneys worth, trust me. I've never had a cockroach in my bra again ever since; definitely an investment worth 1000 dollars.
Other companies will try to offer cheaper solutions, such as filling the breasts with linoleum or even just making lead bras. But, while less hard on the wallet, these attempts of solving the problem will only stall the inevitable.
So, don't settle for cheap, temporary alternatives! Get lead in your breasts NOW, and watch the cockroaches scurry away!
