Our thick black reeds are designed to be used with our 165ml diffuser bottles. You can fit 6 of these reeds into our 165ml bottle. Fibre reeds are custom made for use in reed diffusers and tend to clog less frequently than rattan reeds. The black fibre reeds are more densely coloured than eReeds, with a pure black appearance, even when unused/dry. These fibre reeds are strong and evenly coloured, delivering an excellent aesthetic finish to your product. Each reed is 6mm thick and 175mm long. An excellent alternative to rattan or eReeds, available in black.
