    Rubber ring doesn't last

    2 out of 4 lids of the same product (different sizes) have had two seals from the lids come off. Therefore the lid can not suction on. I paid a lot of money for these, thinking they would last a really long time. I've had them for about a year, and only ever hand washed. I'm now waiting on the other seals to fall off. I'm very disappointed and would not recommend

    No Plastic!

    I love these containers! Unlike many of the glass containers out there, these onyx ones have steel lids rather than plastic ones. As my old plastic storage containers wear out, I'm slowly replacing them with these. This size is pretty small, useful for packed lunches and really good for things like humus, dips, yoghurt, or portions of baby food etc.

    Delivers all it promises. Is quite small.

    I really like this container.

    It didn't get full stars as the top kind of 'indents' and compresses some food/ can't fit as much in it.

    The glass bottom is great for around the house use and i like having the lid for saving food (eg, saving leftover hummus or dips).
