Everything is born into this world and everything will die, in time, even the world itself and the sun upon which we depend and the universe of which we are a part.
Existentialism aside, the quality of our products will only last so long. Scents will fade out of the soaps probably fastest (don’t worry, the punch and power of them is still good! but the smell may not be as invigorating). The anointing oils and the spritzes will likely hold them the longest.
But we don’t know how long. So screw you, best before dates. Instead, we give you a birth date, so you (and we) know when we made it and can make your decisions accordingly.
