I ordered these, and some other items from Elephant Box, to try as an alternative to plastic. The seal is excellent on the two smaller pots but not perfect on the largest one. That is my only criticism and I expect to do with the size rather than any fault. I’ve used them for storing things like humous in the fridge and for transporting lunch. Even though they do seal well, it’s not the sort of seal I’d feel comfortable just chucking into a bag as the lid could get knocked, breaking the seal and making a big mess.
The second photo shows the Seal and Go Trio pots next to one of the Seal and Go Snack Pots.
Great size and leakproof. Very happy with quality too.
