Bigger than I thought, but that would be my fault for not paying attention to the different choices available on the same product page. It is set to default to the 21 egg capacity box, so that's what I got. That's fine. I still use it, but I wanted a slimmer option (which was pictured at some point) and that's what I thought I was ordering. Just be aware and click the correct size option if you don't want the big one it defaults to. THE LID DOES NOT LOCK. I didn't see any reviews that mentioned this, so I'm mentioning it. The lid simply lays on top, with 4 little corner lips that fit down inside the opening to hold it into place. If you tip it A LITTLE sideways while carrying it, the lid doesn't fall off, but if one of your kids tries to handle it (it's heavy when full), and they tip it too much, you're losing some eggs for sure. IT IS HEAVY -- The EMPTY box is already heavier than the dozen carton eggs you're used to handling. Imagine it full of eggs. Yeah. Something to consider. If you have smaller kids who like to help you cook - maybe you can have them take eggs out of it, leaving the box itself in the fridge. They may not be able to carry the whole box to wherever you are prepping your meal without some drama and possibly a clean up. THE FIT: I have hens who just started laying a few months ago, so their eggs range from small to medium large right now. Most are Medium and fit in the box fairly well. The cups are larger than the eggs (even the Large ones) so they wobble a good bit but I haven't had any break from that. The small eggs are a little trickier. The cups do not have gaps cut out of them for your fingers to grab the eggs at their middles, like a commercial carton, so you are grabbing the eggs near the tips. Not a big deal with the med/large eggs, but with the smaller eggs, this is harder. However, since the cups are larger than the eggs, I can get my fingers down a little further on the small eggs to lift them out easier. My fingers are pretty slender though. If yours aren't, you're going to have a harder time I think. My husband can't pull the smaller eggs out at all, and has a harder time with the medium ones than I do. There looks to be plenty of room above the eggs for even Jumbo eggs to fit with the lid closed. That's good if you're storing jumbo eggs. If not, then, that space just increases the odds that your eggs are going to come out of the cups and break inside the box if it gets jarred too hard. When you're used to a store carton that hugs the top of the eggs so they don't move as much, this may take some getting used to. The lid is a good flat spot to store other things on top of in the fridge if you don't mind moving those things out of the way every time you want your eggs. You could also just leave the lid off all together so you can access eggs without messing with the lid, while leaving the box in the fridge all the time. Overall, it's a nice sturdy box that seems like it won't break easy at all, and I like it. It's a very smooth plastic, so it's easy to wash. It takes up more room than I anticipated in the fridge, but if you wanted a 21 egg capacity box in the first place, you'd expect that. I've made it work. I think, in the Summer, when all 7 hens are laying, I'll probably be glad I accidentally got the bigger box. I like being able to see through it to see how many eggs I have. Also, my hen's eggs are a pretty mix of blue, green, cream, pink and brown and I like being able to see that every time I open the fridge. I do wish the lid latched shut, but since the eggs have so much room to fall out anyway, It may not be as helpful a feature as I imagine. I just find myself being very careful with it, aware that it's harder to grasp the eggs well when taking them out, and aware that if I jostle that box hard enough, some eggs are probably going to break. It's not that big of a deal. I don't often take the entire box out of the fridge.
