Where to order extra pads?
AmazerBath Lotion Applicator comes with 4 pads, which should last a good long while since they can be washed/rinsed off. It may be more cost effective to purchase the set than just the pads alone.
What is the material the pads made of?
The pads are made from EVA material that is soft to your skin.
Would this work with oil or something more liquid than lotion?
Definitely. And has 4 additional sponges which you can use for different products and wash.
How often should the pad be changed?
The pad is gently washable and wipeable so you should change the pad when you feel necessary.
How do the pads stay on the handle? Won't they slip off during use?
AmazerBath Lotion Applicator does not slip at all, it works great.
