2 "Design flaws" Paul britton 22 February 2021 This does just about serve its purpose, providing you flick it in the right way to actually get flour to come out of the holes. The major problem is that the upper part doesn't lock or screw onto the base in any way, so there's a constant danger of it coming off and exploding flour across your whole kitchen. The clear plastic lid actually sits more securely, so when you try to remove this you'll end up pulling apart the sifter by accident more times than not. Wouldn't recommend. A note from the team Thank you for your review. We’re sorry this sifter hasn’t been suitable and we’ve been in touch. Our Mary Berry with Lakeland flour sifter, 18614 maybe a suitable alternative to try.
