LocknLock Door Pocket Canister Storage Container 750ml 5 "Great product" Mr Williams 22 December 2020 Great clear jar that fits perfectly in the fridge door, the square profile with rounded corners sacs space and slots right up to the corner. I’ve been using it to store my sourdough starter with great success. Unfortunately the powerful brew managed to blow the top off which broke hitting the ceiling. This shows how airtight the jar is. The tips are universal so I have swapped it from my 1 litre jar for now. Would be good if I could buy a new lid to save some plastic.
