🌈【MATERIAL】: Wood 🌈【Package includes】: 30 sets wooden candle wicks 30 iron Shelfs Size: The layer 1 of the double-layered wooden wick is 5.1 x 0.5 inches and layer 2 is 5.1 x 0.2 inches in size. 🌈【WARM TIPS】 ⭐1. Please make sure soak the candle wicks in wax (molten) 5-10 minutes before candle making. ⭐2. . It's important to trim the wick close to the wax so it has fuel to ignite. If won't stay lit, try to trim shorter, 1/8" is perfect.If the wax wick is too long, it will not absorb the wax at the bottom. If the wax wick is too short, the flame will be too small or unable to burn because the wax oil covers the wax wick. If won't stay lit, try to trim shorter.
