Replenish

I think that this product is fantastic because by adding water at home and only using a portion of the concentrated liquid at the bottom means that it lasts a lot longer at home. The bottom is then replaceable so you don't have to buy a new bottle every time you run out. It sames on plastic wastage and also reduces the carbon footprint of the product because the company doesn't have to make a whole new spray bottle every time.
