Milk bottles are used between 20 - 50 times each before they get recycled, compared to the plastic bottle's once, most of which still go in landfill.
The only negative in the milk bottle story is the foil tops. They drive us mad trying to constantly balance the crumpled foil on top of the bottle, they certainly don't keep the milk fresh. Lets face it, once you've opened your bottle they're pretty pointless. So we came up with the idea of a reusable silicone top.
If you get your milk or juice delivered, you need these.
