After some training, I learned that there was nothing worse than refrigerate the commercial egg boxes (or market) in our fridge. Indeed, it is full of bacteria, microbe, it would be like putting a dirty diaper in the fridge !!!! (Beurke!). This box is used to refrigerate eggs (of all sizes !!!! even large!) Without bringing bacteria that come with the original box !! Caution still small eggs because they might break if you abuse the box (this remains eggs !!!). And a significant feature, it can go in the dishwasher !!! Great if you are manic !! ;-)
