The set contains 6 black diffuser caps, each with a diameter of 3 cm. The caps are made from black plastic with a matte-satin surface. The simple, dark tone stays in the background, so the colour of the glass and the liquid inside the bottle remains the focus. The set fits the RDBot-11, RDBot-12, RDBot-13, RDBot-14, RDBot-15, RDBot-16 reed diffuser bottle families, so caps on existing diffusers can be unified or replaced.
What the set of 6 caps is for
The diffuser caps are mainly used to close the neck of the bottle and to provide a decorative finish. When the bottle is not in active use — for example before transport or longer storage — putting the cap back reduces evaporation and keeps more of the fragrance inside. The pack of 6 is practical if you run several diffusers in parallel or want a consistent look across multiple points of a home.
Material and finish
The base material is black-pigmented plastic in a matte-satin finish. The surface is durable, shows fingerprints less and can easily be cleaned with a soft cloth. Black works well with most glass colours and reinforces the modern, clean character of the 3 cm RDBot-11/12/13/14/15/16 bottles — it fits offices, shops and minimalist home interiors equally well.

- Other bottles with a compatible 3 cm neck diameter
Before purchase, it is worth measuring the outer diameter of the existing bottle neck and comparing it with the 3 cm size. On bottles with a different diameter, the cap may not fit firmly or sit stably in place.
Typical use cases
The set is a practical solution when an older bottle is missing its cap, when an existing cap is damaged or discoloured, or when you want unified caps across several bottles. The reed sticks can be placed back in the usual way after the cap is removed, and during use the cap normally rests beside the bottle.
Cleaning and care
Wipe the cap with a soft, dry or slightly damp cloth. Avoid strong solvents and abrasive cleaners, as these can damage the surface coating. With appropriate cleaning and dry, cool storage, the cap maintains its original appearance over a long period.
