A B- CORP with an obsession for reducing single use waste is how I would describe U-Konserve! Their dedication to ethical sourcing, sustainable materials, responsible consumption and community engagement is impressive. On a personal note, I have been using my U-Konserve lunch box and containers for years - 9 I think! I have found them to be be extremely useful and obviously very durable. I recently upgraded the lids on a couple as the new silicone lids are much more flexible and it's handy to be able to see through them. It is a bit like having a new container, without the cost and without the waste. This is product sustainability at its finest - no inbuilt obsolescence with U-Konserve!
