So those are canisters under the foil. So what is there to check? Well, not so much. The price was right for the amount that was included in the package. So everything is fine. They're generally consistent in quality, but the filling isn't anything special. I would call these simple containers but no protective packaging (beyond a simple drop or dust). The seals are not airtight (which is normal) but the seal tightness between the containers is light. Some close well and the lids stay on, some don't. That's why they get an average rating of 3 stars. If you want something better, you have to spend more. If you are just looking for a simple container then they will suit you. Hope that helps.
