Getting into candle making? These Xrten wicks are a great basic supply. You get 100 pieces in the pack, which is plenty to start with. Each wick is pre-waxed cotton, about 15 cm (5.9 inches) long, with a small metal tab (sustainer) at the bottom. The tab is about 1.3 cm in diameter and acts as a wick centering device – it helps keep the wick straight and in the middle of your jar or mold while the wax cools. You can easily trim them to your desired length. They're made with heat-resistant glue to stay put in the hot wax. A quick tip from the seller: be careful not to go overboard with dyes or scents, as too much can mess with how well the candle burns. These are simple, economical, and essential for any DIY candle project. Good value for a big batch.
