This wick is the best choice for gel candles.   It has a cardboard core which helps it stay upright in a pool of melted candle wax or gelwax.

Snip the wick after blowing it out as a ball of ash tends to form at the tip if the wick is relit several times.

Use Wick for Gelwax in gel candles with a diameter of about 40mm – 70mm..  http://www.candledeli.co.za/index.php/gel-wax/

Use metal wick sustainers to anchor the wick to the bottom of the glass.   http://www.candledeli.co.za/index.php/sustainers/
