Nope. Those aren't dildo storage cases (although, a dildo storage case wouldn't be such a bad idea). Those are actually Banana Bunkers. They keep your bananas from bruising when they're banging around your briefcase/back pack all day long? Yeah, not the greatest invention but usually anything that looks like a prosthetic penis grabs the attention of potential customers. And marketing 101 states: Anyone that views your product, either voluntarily or forcefully, is still a potential customer.
So go get yourselves a Banana Dildo, uhm I mean Banana Bunker. Yeah, Banana Bunker.
