Patron himself describes it this way:

"So the key to every heart is sincere love. Love + keys = a keychain with Patron and a heart.
If your sweetie often loses his keys - give him/her this keychain. It will be a pity to lose it, because it is about love. And love is not something you throw away."

We'll add:
Patron's size - 40x20 mm
Material - metal.
