These vacuum insulated can coolers are perfect for hot or cold drinks.  There are two lids included. The first allows for it to be used as a can cooler (fits regular cans, skinny cans, and standard bottles) and the second lid turns it into a 16oz tumbler. Each one is made by hand, so customization is possible.  
 
Each can cooler comes with a rubber base and a straw.  These are not dishwasher safe as the dishwasher can break the vacuum seal and allow water to seep between.
