When it comes to silly-season gift-giving, presents don't get much silly-willier than this. Drop this perfect pecker into a bowl of water and it'll grow to 600% its orignal size. You can't do as much with it as you can a real man, but at least it won't fart in bed!

Another fun novelty gift from the Grow Your Own range.

Keeps growing for 72 hours.

Stays grown as long as it stays wet.
