My favourite canisters would be something durable, quirky and eye-catching, that seals coffee 100% effectively.

However, due to the nature of my present living space on a narrowboat, I have gone for these practical plastic containers. The reason is that, oftentimes the boat gets rocked and items fall off shelves.
If I'm honest though, I'd love to replace them with nicer ones, but it's just not a priority right now:)
