Pre-waxed wicks for container candles: pure cotton, and cotton with an interwoven paper core that holds itself upright while the wax sets, in 12, 15 and 20 cm and packs of 25 or 100, plus wooden wicks with metal clips. Fix each wick to the base with a wick sticker and hold it straight with a centring bar. For help matching a wick to your container and wax, see how to choose a candle wick.
