The box says this pleasure pump enlarger is for novices. I suppose that's a fair statement since there's really nothing too complicated about using it. However, the picture on the package suggests single-handed operation, when in actuality the user must pump with one hand and cover the air-release hole with the opposite thumb. Oh, well, If your dick doesn't grow, at least your forearms will look like Popeye's with all the rapid pumping. Use lots of lube and have fun looking at boxcover boy Kevin Kramer.
