The most sustainable cup on the market, which supports the circular economy, is ideal for all environmentalists who adore coffee. Wondering what it’s made of? It is made from USED COFFEE GROUNDS, which is recycled and reused. Due to the material from which it is made, the cup is very light, but at the same time, it is tough to break and destroy (for all those a little more awkward). It’s dishwasher safe.
