Pump compatible with Aesop 500ml bottles I was using it with Geranium. For those whose pumps on Aesop 500ml bottles have broken, for shampoo, conditioner, hand soap, body wash, hand cream, etc. It also fits Aesop mouthwash bottles. I have only checked if it can be set on Aesop 500ml bottles, so I do not accept questions or returns regarding installation on other bottles. Please understand this beforehand.
