I was so excited to be able to review these storage containers. First, because our collection fo containers is a mess. Secondly, we are on the lookout for a better quality storage container. My first thought upon their arrival was that they are huge! I was thinking leftover dinner sizes and the largest one is really the size of a full meal. The smallest container of the four is a regular sandwich size.
The lids have four snap down flaps. You do not have to line anything up for them to work. Flipping each side down does create a small snapping sound. Each container is clear so you can easily see inside.
The containers have a vacuum seal. Once you have closed the lid, use your thumbs to push down on the top in any clear area. You may hear a small hissing sounds as the air escapes.
The valve pictured above is the really unique part of these containers. It is where the air is released to create the vacuum effect. To release the vacuum, lift the green tab upwards. Once again you may here an air whooshing sound. The white circular dial is adjustable to set the day of the month, so you know how fresh your contents are. This for me is the least effective piece. I tried turning one of the dials when I first got the containers and couldn't get it to turn. I don't really mind because honestly, I don't see myself using it.
Instant vacuum freshness without pumps, motors or confusing parts; Simply press down on the lid and air is forced out via the one-way valve.
Patented valve removes excess air to reduce naturally occurring bacteria; It also releases pressure to prevent spills and splatters in microwaves.
Wave pattern on the bottom of each container keeps cut fruit and vegetables elevated from water and juices.
Handy date dial allows you to record when food was first stored and monitor days kept in the refrigerator.
BPA-free, stain-resistant, shatter-proof and as transparent as glass; Freezer, microwave, and dishwasher safe; Satisfaction guaranteed.
