You can tell by looking at me that my big a$$ can crush anything. And my thick, strong thighs are no exception. I take these air filled packing pillows and display to you what I would do to you if your head were between my quads. One after another, squeezing, and with no effort, POP...POP...POP, goes each one. These were made to protect items being shipped in boxes, but they offer no protection from my damaging quad pressure!
