Vintage light yellow depression glass in a concave window type pattern. I used a sugar bowl to make this night light so it is somewhat larger than the tea cups and candle holders I usually have listed. It measures 2 3/4" high and is 3 5/8" across at the top not counting the handle. I use industrial strength glue to make sure the cup is secure. A 4 Watt bulb made for night lights is included.
