La Tee Da's Elite Style 2-Piece Replacement Wick fits all brands of Regular Size fragrance lamps with a top opening of 1/2 inch. Will fit any brand of Regular Sized fragrance lampe sold by Courtneys. The Gearhead or Scalloped style wickstone consumes fragrance lampe oil at a faster rate than the round style wickstones and does not have a center hole. This Wickstone has a two-piece top with a floating center. Our Customers report this new wick stone style clogs less frequently and seems to last longer. NOTE: WILL NOT FIT MINI-LAMPES
