⭐️50mm rubber stopper cap for balloon and demijohns⭐️

✨ The 50 mm diameter balloon stopper cap is an essential accessory that protects the neck of the bottle from dirt and damage. It is made of durable and flexible PVC material, which guarantees tightness and protection against the penetration of bacteria and other microorganisms. The stoppers have a hole into which you can insert a fermentation tube (glass or plastic).

✍️ The size of the stopper corresponds to the outer diameter of the bottle neck, making it universal and suitable for most balloons. The stopper easily slides onto the bottle neck and locks securely, providing protection against dust, dirt and moisture.

⚠️ Before first use, we recommend rinsing the cap thoroughly with warm water and dishwashing liquid, then drying it thoroughly. This is to remove the layer of silicone left from the manufacturing process, which can cause the cap to slip out of the bottle.

⚙️ The cap is suitable for bottles with a capacity of:

• 10 -litres;
• 15 -litres;
• 20 -litres;
• 25 -litres;
• 34 -litres;
