It seems more for self-gratification if anything.
With a typical packer I doubt anyone's going to see it. With a STP packer I doubt anyone's going to sneak a peak while you take a tinkle.
I'm buying a Mr.Limpy because it's the cheapest packer (rolling socks seems too hard and condoms would be expensive) and just because it looks fun to play with.
It's cotton-candy pink, and I seriously doubt anyone has cotton-candy pink skin. Even than it couldn't pass as my skin tone unless I put makeup on it, since I'm more like a caramel tone.. Or something; I don't really get the coffee-candy shades.
