If the supply of a certain commodity is low or of poor quality, you can overcome this by creating your own.
The same thing applies to penises; if there isn’t enough of them out there or they just don’t satisfy you enough, you can grow your own.
Grow Your Own Willy is a 4.5cm penis that can fit in your pocket and will grow to 6 times its size when you submerge it in water. When you take it out of the water, it will shrink back to its regular size.
A great gift to give to your single friends until they match with someone on Tinder.
