I purchased this set to replace my old canisters as they began to look a little dull. I must say they do look better on the picture .. but most things normally do.
They arrived quickly and were very well packaged. The canisters themselves are black enamel finish and are a made of a 'flexible' metal, I can basically bend the opening of the canister without too much force, which isn't a issue but if they were dropped I would imagine they would become dented. The lid does show finger marks when touched but I find wiping with kitchen roll keeps them looking lovely.
Overall I am happy and find the shape of the lid quite contemporary. I have black delonghi appliances and these canisters look lovely alongside. I wash them in warm soapy using a soft sponge, I would personally not use abrasive sponges as I feel they may scratch. I am not lucky enough to have a dishwasher so can't advise if they are dishwasher safe, sorry.
Hope this review helps.
