Tightpac America, Inc.airtight Container, Solid Black, .29-Liter/9-Fluid Ounce

Does a good job at keeping odours in, might not fool a trained dog but thankfully haven't had to test that. Solid, robust materials. Survived being dropped from a height of ~3m. Press button mechanism seems sturdy

This was quite small so I used it for cinnamon and Christmas spices. It was mostly odourless once sealed but its not perfect and there was some decay evident in the faded colour and loss of intensity of contents. Not perfect but probably the best you can get. This container is slightly smaller than a drinks can

Great buy! Keeps tea/coffee as fresh as when the pack was opened.

Works decent for smell proofing however it is not the listed item, it has clear plastic instead of black.

Good for sealing smelly things in

Very good I have had many over the years

Does what it says on the packet, good buy

Nice but cracks easy.
