I read an article about using these instead of the throwaway paper sleeves you get on paper coffee cups. This really works! Though they are thicker than the paper sleeves, they really do keep the heat or cold away from your hand, and best of all you aren't wasting paper or requiring recycling (which sounds good in theory but is actually still worse for our environment because of all the chemicals needed to process). So, environmentally friendly + keeps your hand away from the heat/cold = perfect purchase.
