About 3.5" x 3.5" wide. Hole on the bottom to fit a tealight candle. WARNING these get hot if under a real flame, I find that it is better if you use a battery powered light. 
 
This product has multiples, the one you recieve may look slightly different than the one photographed. 
 
There are two different options in selecting these. Left has holes vertically and Right has holes randomly. 
 
You may see some little crack on the inside near the stem. These occured during the drying as this section was thicker. These will in no way change its function or make it more fragile*
 
Each with my stamped signature and MADE IN THE TETONS mark on the bottom of mug. Please embrace "perfectly imperfect" as this proves the pot to be handmade. All pieces are funtional and food safe, no funny business. Anything with GOLD is NOT microwave safe. I recommend handwashing for the longevity of handmade, but secretly put everything ceramic in the top rack of my dishwasher.
