Lock the lid, secure the vacuum
Most vacuum containers rely only on suction.Over time the seal gradually relaxes. Mechanical locking prevents that drift.
Once sealed, the lid stays physically fixed —not slowly easing back.

The seal is trustworthy, a few days later and it was still fully sealed. That alone sold me.

Update: I saved more than $2000 over the past 8 months since i eat out way less. Leftovers actually stay good so I'm not throwing food out and ordering again.

Good upgrade, meals tasted fresh like same day cooked. No weird fridge smell, no loss of vacuum. feels reliable. another thing about it is that it's microwavable and also stainless steel which makes it much easier to clean

Recent Reviews
Best lid I’ve used so far, good size. The seal feels trustworthy every time I close it. Only thing I wish is that Preserva sold extra lids separately — I’d buy another container just to match.

I’ve been slowly replacing my glass containers and wanted something less heavy and easier to clean. These Preserva containers are much lighter and still feel sturdy. The vacuum seal works well and they fit my daily lunches perfectly.
12-13-2025
Update after a few weeks: be careful opening the clips — they’re tighter than expected. I actually hurt a fingernail trying to pop one open.That said, they stack well, nest nicely, and I do like stainless steel over glass for durability. Sizes run a bit smaller than I imagined.
12-05-2025
Good quality and does what it says. Solid stainless steel, good sealing, and overall well made. I’ve been using them in the fridge and freezer without issues. The vacuum feature works as intended and feels reliable.

Nice set for meal prep (with minor quirks) These Preserva containers look great and feel substantial without being heavy. I like the clear lids and the vacuum function. They nest well and don’t take much space.One thing to note: food takes a bit longer to reheat, and it cools faster than my old containers. Not a dealbreaker, just a heads up.

been using these Preserva containers for work lunches. the stainless steel feels solid and the vacuum seal has held up so far. the lid can be a little firm to open, but i’d rather that than leaks. overall happy with them.
