Really cute set. I just got it so I haven’t used it yet. Nice seal on covers so flour etc. should  be fine. Packed so well! I am giving it a 4 because two areas on two of the cannisters were missing a bit of red paint. The covers hide the spots which are covered in dabs of white paint. Can’t wait to do my spring cleaning so I can put them on my countertop. No more pulling big heavy containers down from the top shelf while standing on a stool. I love what I see!
