Our natural whisper wicks are available in both single-ply and booster wick varieties and are sourced from sustainable mills. Whisper Single-ply wooden wicks work best in paraffin waxes and blends and in some coconut blends. The Whisper Booster wicks work best in soy and vegetable-based wax blends. Whisper wicks are the quietest wooden wicks, with little to no crackle, and provide a beautiful horizontal flame shape. Be sure to conduct a burn test when altering any aspect of your candle to ensure optimal wick performance. Check our Wick Selection Guide to find the right wick for your candle-making project. Important note: this is a custom wick that requires an additional 1-3 week lead time and a $7 handling fee applies to custom wick orders.
