I would tell you that you mean the world to me, but that would be an understatement. So I prefer to tell you with this card that for me, you are an infinite universe, full of stars, unknown galaxies, constellations, and the occasional black hole, and that all of this makes me fascinated to be by your side every day. This "You're My Entire Universe" greeting card is perfect for congratulating your significant other.It has A5 dimensions (21x14.8 cm).Comes with matching envelope included.
