What you receive: This package includes 6 catalytic wick replacements in 2 colors (silver and gold), with 3 pieces of each color. The sufficient quantity provides replacements for air-controlled catalytic burner wicks. Harmless and strong: These oil lamp wicks are made from a blend of clay materials, forming a precise ceramic structure. The outer ring is constructed of metal, which reinforces the wick's durability and helps maintain its shape. Good oil absorption: The well-woven oil lamp wick offers excellent oil absorption. It can be used with aromatherapy lamps and essential oils to efficiently diffuse fragrance, helping to freshen the air in your room. Please note that aromatherapy lamps and essential oils are not included. Size information: The ceramic diameter measures 0.71 inches (18 mm), compatible with most catalytic aroma lamps. Please verify the mouth diameter of your aromatherapy lamp to ensure proper fit. Practical usage: After the wick absorbs essential oil through the cotton core, the oil adheres to the wick’s pores.
