These shades measure 4"x4"x2.5".
These ceramic candle shades work like a candle topper to circulate the air flow better while the candle is burning for a cleaner candle. The star cut outs on the sides look really neat while burning and make an illuminating light pattern on nearby walls. This shade fits all jars with a 3" opening. Fit all standard mason jars, and 12oz Victorian jars for example.
