Confezione singola di coperchi per bottiglie d'acqua da 3 e 5 galloni, coperchi in silicone da 55 mm per bottiglie di acqua minerale, a prova di traboccamento e perdite, riutilizzabili.

Leak-proof bottle cap: Fits all standard screw-top water bottles with diameters of 55 to 60 mm. This bottle cap offers a stronger seal and has been tested to ensure no leaks or drips even when stored upside down. Key design details: Two lugs on each side for easy installation and removal. Widened anti-slip grooves prevent the cap from falling into the water. A larger, thicker stopper provides a stronger seal, firmly locking the bottle neck. Reusable food-grade silicone material: Heat resistant and dishwasher safe. Unlike plastic bottle caps, each silicone bottle cap can be reused thousands of times. Easy installation and removal: This reusable bottle cap can be installed or removed in seconds. Two lugs on both sides of the cap allow for quick and easy installation, and a gentle lift makes removal effortless. So simple, saving time and effort. Home and travel essential: This 5-gallon bottle cap is lightweight, portable, and easy to use. Suitable for all types of water dispensers without affecting hot water heating.
