Green House Handy Beer Server for Canned Beer, Ultrasonic, Push-Type Switch, Blue GH-BEERIS-BL

●Handy beer server that attaches to canned beer.
●40,000 vibrations per second. Finely textured, creamy foam created by ultrasonic waves.
The creamy foam is generated by ultrasonic waves. The key is the frequency. After thorough research,
we have set the vibration frequency to 40kHz. This means it vibrates 40,000 times per second at an incredible speed.
●Freely add more foam.
Instead of extracting foam from existing beer, this product uses a method of adding foam from new beer.
You can easily add foam while preserving the taste of the beer below.
●Easy to attach! Compatible with 250ml/350ml/500ml cans.
●Even more stylish, even easier to use.
●Hygienic, with a spout that can be washed clean.
