The hermetus is the bottle’s best friend! It helps turn difficult screw caps, pops off crown caps, and provides airtight bottle resealing, allowing you to save your beer for later. It’s unique and convenient to carry and use.


Product fun fact: the hermetus is made in Germany, so the illustrations of its use inscribed on its body are captioned in both German and English!



Reviews from real customers:

“Do you like beer? Do you like carbonated beer? Do you like to savor your beer? Do you like fine German engineering? If you answered YES to these questions then buy this device. I own 3 and have given this as a gift a half-dozen times. First, it's a serviceable opener. Second, the silicon sleeve really does work to save beers. I've capped a 1/2 full bomber and let it sit in the fridge for 3+ days and SNAP it pops open and pours beautifully. WOW! If I had to deduct any stars it would be that it doesn't fit most corked bottles. Still, that's pretty minor and not unexpected”

“Very happy with this purchase! It's sturdy, well-designed, and works exactly as desired. When used to re-seal a bottle, the seal is so complete that the bottle can be turned upside-down without leaking. Kept a bottle of Coca-Cola perfectly fresh and fizzy when re-opened over 24 hours later. Would definitely recommend this bottle opener.”

”This resealer/opener is one of the best tools I've gotten for beer consumption. It's easy to use, works exceptionally well at opening and resealing those big bombers that you open for yourself but can't (or don't want to) drink all at one time. Or better, buy a coupe and you can sample a couple beers like you're at a tasting room and this gizmo will keep it perfectly sealed for a couple days. I will give these for gifts at Christmas and I'd even buy a couple more for myself. I can't recommend it highly enough.”
