What you receive: This package includes 6 catalytic wick replacements in 2 colors (silver and gold), with 3 pieces of each color. The quantity provided is sufficient for regular replacement needs 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 from metal, which helps maintain the wick's shape and provides added durability. Good oil absorption: The well-woven oil lamp wick offers strong oil absorption. It can be used with aromatherapy lamps and essential oils to efficiently diffuse fragrance, helping to freshen the air in your space. 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 standard catalytic aroma lamps. Please verify that the mouth diameter of your aromatherapy lamp matches the wick size before purchase. Practical usage: Once the wick absorbs essential oil through its cotton core, the oil adheres to the porous structure of the wick. This catalytic burner wick is commonly used as an aromatherapy accessory to help disperse fragrance and purify indoor air, contributing to a pleasant environment.
