Small Heating Cover Fits Like a Glove Over 3-Inch Alcohol Burner

It's a perfect fit for the small 3-inch wide Alcohol Burner. This setup gets hot enough to boil a small pot of water, so I wouldn't recommend putting a Dollar Tree Ceramic Coffee Cup over it unless you want to make it crack and explode. The stainless steel lid makes a good base to put underneath the Alcohol Burner. The 4 tiny "feet" at the base of the cover fit snuggly into the inverted lid. I love it, but it could still turn over pretty easy. Not exactly safe to leave it burning unattended. One swoop of the dog's tail and this thing becomes a molotov cocktail!!!
