Now here's a clever idea. To replace the disposable drink collar on coffee cups (one more piece of cardboard to throw away or recycle), Scott Amron created a cup with a built-in sleeve that swells like magic to protect your hand. The cup replaces the cup/sleeve duo so ubiquitous in coffee shops and restaurants, and is still biodegradable and recyclable.
We hope that our favorite coffee shop switches to this design -- we'd love to see it in action!
