The Cup Cooley ($4) is a silicone coffee cup cozy that not only protects your hands from the heat, it also insulates the cup and provides a truly superior grip. These reusable sleeves fit most standard cup sizes and are made from durable heat- and slip-resistant silicone. The compact reusable design easily stores in your pocket, purse or car, so bring one along to your favorite coffee shop to replace those wasteful disposable cardboard sleeves that just end up in a landfill. This is literally a much cooler solution. (via Michael Kiely)
