Alumínium Kupak Boston Jantár Üveghez (230ml & 500ml) – durable, reliable accessory for home storage
This cap is designed specifically for Boston amber bottles (in both 230 ml and 500 ml sizes). It is made of aluminium, lighter and more durable than the plastic version. The inner liner ensures a tight seal. The cap closes quickly and tightly, allowing safe storage of essential oils, hydrosols or carrier oils.
Material and finish
The piece is made from alumínium, with carefully checked production. The surface is smooth, the edges softened, so handling is safe. The cap cleans easily, can be refilled, and is reusable many times – a practical detail for anyone who appreciates clear, sustainable storage at home.

How to use it
Simply screw the cap onto the bottle – do not over-tighten. The inner ring is flexible, so a gentle turn is enough for a tight seal. Equipping several bottles with the same kind of cap results in a tidy, easy-to-manage storage system on a shelf. It is also reusable, making it cost-effective in the long run. It is a small accessory that will serve well for many years, also adapting to different liquids over time.
What to pair it with
The piece fits naturally with the Boston amber bottle family. If you store essential oil blends, hydrosols or your own homemade cosmetics, a unified packaging system makes shelves easier to organise and label. Refillability is also a friendly choice for reducing household waste.
Care
Wash in warm soapy water, rinse thoroughly, and let dry completely before reuse. Use only gentle cleaners. If you store essential oils, clean residues regularly – some oils can soften plastic over long periods, in which case an aluminium cap or a glass-stopper alternative may be worth considering.
