CDN 8, 15cm Tabbed Candle Wicks are a pure cotton with paper core flat braid style wick suitable for Soy, Palm and Paraffin wax.  They contain no zinc or lead.
 
They give a burn diameter of approx 50cms... this is only a starting point different fragrances will effect burn diameter so your own testing is needed and you may need to choose a larger or smaller wick.  This measurement is only a rough guide.
 
These wicks will have to be trimmed before relighting.
 
Tab size may vary depending on availability.
