Fridge Binz Lidded Egg Holder 5 "Love it - would recommend" Mrs Warrington 09 April 2015 I bought 2 of these, 1 for the caravan. Found I often use 2 in the house as will stack in the fridge. They are NOT dishwasher proof- as I found out when I washed it - and it warped a bit! However, a bit of boiling water from the kettle and I straightened it out. My fault for not reading the instructionbs - though as most items are now dishwasher-proof, I just assumed this was. I give it 5* as the warping was my fault.
