Last Updated: 2026/04/03, I saw a sealed can with one-way exhaust on TB. I haven't seen it before. I only know that the bag has exhaust. Is this jar better for preserving coffee beans than coffee bags?

I saw a sealed jar with a single row on TB. I had never seen it before. I only knew that there was a row in the bag. Excuse me, is this jar better for coffee beans than coffee bags?
