Usage Instruction: These candle wicks are thin, so please do make sure to use a double layer wick with a metal holder to ensure the burning effect. If you use a single piece, there is a high possibility of combustion problems. About wax: Some people like the natural and elegant nature of wooden candle wick, but it is not as easy to burn as cotton wick. Remember to double layer them in the same metal holder for a strong enough flame so it doesn’t go out. Also, you need to use a better burning wax base, such as soy wax, paraffin wax, etc. If your wax is not a common wax, please consult us first before placing an order. Widely used: Our candle wick can be used in candle jars up to 4-8oz. If your candle jar is larger than 8oz, you will need to use two or three groups of candle wicks. Natural Experience: The pure natural cherry wood, without any additives, allows you to fully enjoy the burning experience of the natural candle core, and the sound will also have a great effect on enhancing the atmosphere. 250 pcs candle making wicks kit (50 sets): 100 pcs 13x1.3cm (5.1 x 0.5inch) wooden wicks, 50 pcs metal base, 60 pcs wick sticker and 40 pcs warning safe stickers.
