Stash your drink in a Self Help Book.
A tongue-in-cheek gift for friends who need a little self improvement.
#Fill the flask with the recipient's favorite tipple, or if you really want to push the boat out, nip into your local key cutting shop and get the flask engraved!
Trick your least saintly friend and watch their shock and surprise at receiving the 'good book' on their birthday, only to discover the hidden booze container inside.
