Finally, a cool looking coffee cup you can re-use again and again and again.
Made from silicone, it is firm but flexible, lightweight but tough, and will withstand 200 degree heat. It is pretty much indestructible. This means it will not contribute to the mountain of discarded disposable coffee cups shoved into landfill, which will never decompose because of their polymer lining.
The 'BYOcup' keeps your coffee warm yet it is cool to the touch. Use it. Wash it. Use it.
A way of enjoying the coffee of your choice, without adding more rubbish to the world.
