Hardcover condoms?

has anyone ever hear or used them before?
if yeah do they protect against pregnancy economically? Um..yeah..people..hardcover is a brand ...not a "hard" condom. Geesh..don't any of you look up info up to that time you answer? I went to the site...and they look really cool. It seem like a fun company...and nearby are so many different kind. Personally, I prefer Trojans...but hey...to each their own.
no!
