Our all natural rattan reeds are 3mm in diameter and 7.85” in length. Our reeds are precision-cut allowing the reed to diffuse lots of fragrance. Package of 100 reeds. Directions: Place 6-8 reeds in a diffuser bottle of reed diffuser solution (fragrance + base). We recommend 6-8 reeds as a starting point, but you may choose to add more. Know that the more reeds you use, the more fragrance is released, and the quicker the liquid is used up. Pair this with our Clear or Amber Boston Round Bottles and Poly Caps.
