When you're camping, you are always nervous to leave an open can of soda or beer on the picnic table. What if an angry hornet falls in? What if bugs, leaves or other debris land in your soda?
Soda can covers solve this problem. The small covers may be rubber or plastic, and they fit perfectly on a soda in a way that is easy to take off. They also have different colors or patterns to help you identify your soda when there are multiple people drinking the same flavor.
They would come in packs of 4-6.
