OXO Good Grips POP Rectangular Food Storage Container 1.6L 5 "New Fan" Mrs Machin 22 October 2020 I am a great fan of lock and lock. But liked the shape of these. They really do what it says on the tin. For those with finger problems they are excellent. The on top of lid button is so easy To use. I shall look at buying more. I don't use a dishwasher. So cannot comment on those qualities. But certainly no pleoblems with hand wash.
