For a starter range, choose a practical mix of 100 ml and 140 ml bottles. The 100 ml size works well for everyday reed diffusers, while the 140 ml Alchemist bottles give a stronger gift and boutique look.

Smaller bottles, such as 50 ml options, are useful for testers, mini gift sets, seasonal samples, hotel-style ranges and lower-price entry products.

Display finished diffusers by fragrance family, colour or gift occasion. If selling components, group bottles with reed sticks, caps, fragrance oils, labels and gift boxes so customers can see the complete making solution.
