Vista Replacement Dish Bowl Lid Cup Electric Oil Lamp Warmer Diffuser 2 1/2" Across 1" Deep

They were too small but they were also very pretty and I didn't want to send them back and to cause you a lot of trouble and I couldn't find the same type with just a little wider diameter I don't like the ones that have the round bottoms I like this one because it was you know vertical just straight up and down but they weren't wide enough I needed another half an inch but they're very pretty well thank you

While this fits well on my warmer, it's really thick bottom makes it harder to heat the oil. I need a new shade for my warmer because I had to leave the thing on high and my shade is now discolored.

This item is not true to size. The measurement is more like 3 3/4 inches across.
