Our wick sustaining tabs are made of galvanized steel sheet, which is not only shiny, but also corrosion proof. There are 3 base diameters for your choice: 12.5, 14, and 19.5 mm, which can be used in tealight, votive, pillar candle and container candle production. The collar height is 4 mm, high enough to extinguish the flame before it gets too close to the glass base.
