Love them. They create a strong, airtight seal every single time, and I can actually taste the difference in freshness compared to using regular lids. I store coffee, sugar, nuts, and even leftovers, and everything stays just as good as the day I sealed it. What I love most is that they’re reusable, I just wash them, dry them, and they’re ready to go again. It feels like such a money saver and way better for the environment than constantly buying disposable options.
