Esilihom 4 Pack Plastic Crate with Handle, Folding Crate Boxes Organizer for Shelf, Stacking Collapsible Closet Container for Home Office Kitchen

Love these for all my stationary purposes, unfortunately doesn't hold my a4 papers or laminating pockets... the stacking capability is very handy as it keeps everything tidy and well kept

This cleverly designed product allows you go click the plastic components together to form a neat stackable set of trays. Unfortunately once you have built a tray by clicking it together, it tends to unclick itself and fall apart! I suspect that by gluing the clickable bits together it will be fine.

The footprint of these is slightly smaller than an A4 page, which to me is a bit of a shame, but they are really useful for things other than A4 sheets. They are made really well. The plastic is strong and resilient, the handles strong. They fold nicely, but are strong and rigid when formed into the mini-crates that they basically are.They are a nice colour and hold a good amount if things - as long as they are smaller and an A4 sheet.

I find these quite tricky to construct. They don't seem to want to slot in without a lot more coaxing than I would expect. And after doing three the fourth is tricky. Once constructed they are sturdy but they do feel weak. There's a photo on the Amazon listing of one containing numerous jars and bottles of sauces etc, I honestly don't think it would lift that amount of weight. The plastic seems lower grade and likely to be brittle. I think they're fine for containing and tidying, for storage of things that aren't too heavy.These fold flat really well so are ideal for travelling with. I'll use them to take camping for our camp kitchen. They're far from awful, just not as good as I expected.
