The pack contains 50 simple 28 mm plastic stoppers used to close 28 mm neck diffuser bottles (RDBot-21..32 series). This format is typically a refill and replacement kit: not a decorative cap, but a functional sealing element that prevents evaporation and spillage during transport, storage and intermediate handling.
What the 50-piece stopper set is for
The 50-piece format is practical when you regularly fill diffuser bottles with your own fragrance blends, or when you run a small manufactory, gift workshop or actively used webshop back-office that needs continuous stock. Each stopper can be replaced individually, so a lost or worn piece does not require swapping the whole bottle or the decorative cap.
Material and finish
The base material is plastic suitable for food and cosmetic use, in a neutral whitish-translucent shade. The stopper attaches to the bottle neck with a friction fit, so it can be inserted and removed quickly while still providing a reliable seal during transport. The stopper is NOT a decorative cap; its purpose is practical, dependable closure.
Compatibility
- RDBot-21 .. RDBot-32 series diffuser bottles with a 28 mm neck
- Other glass bottles with a standard 28 mm inner neck diameter
- NOT recommended for bottles with different (e.g. 18, 22, 24 mm) neck sizes
Typical use cases
It is worth keeping the stoppers ready before filling so the fresh aroma blend can be closed immediately. When putting the diffuser into service, the stopper is removed and replaced with a rattan reed or a decorative cap; bottles not in active use are stored with the stopper inserted again.
Cleaning and storage
The stoppers can be cleaned with a soft cloth or rinsed in slightly soapy water, then stored dry in a closed box, protected from dust. Avoid strong solvents (such as acetone), as these can damage the plastic surface.
