OEMTOOLS 26052 Foldable Magnetic Tray Set, Mothers Day Gifts, Magnetic Tray for Mechanic's Small Parts, Sorting and Storage, Collapsible, 4-1/2" Square, 2 lb. Capacity, 4 Color Gifts for Mom

These are pretty nice. I like that they are collapsible for storage. The magnetic strength isn’t the best but that doesn’t bother me.

I really like these trays. I have 3 sets so far and will likely buy more in the future. The sides unfold / pop up high enough so that it's unlikely anything in them will simply be jostled out. They're light and flatten down to stack and store in minimal room. Fasteners stay put in them well enough that - if you're working with multiple fastener types - you can even stick one type on the bottom next to one side, another on the bottom next to a different side, etc. and they'll usually stay put to keep the different fasteners separated. During re-assembly of your project, you can clearly see how many of a particular fastener you have left. That works much better than the old jars or plastic bags I used to use to hold fasteners during disassembly; where the different types of fasteners often get all jumbled together in one big pile, My only challenge with them is that I've gotten so used to using them on most projects. When I have to interrupt work on one project before it's completed and move to another, I typically found that the prior project was occupying one or more of these trays that I now needed for the priority project. But I don't want to unload the fasteners from the first project and put them in a container as one big pile. That's why I've bought several sets so far. Highly recommended.

Nice set of trays, cheaper compared to tool truck ones and same quality. Only set back is the black tray is not magnetic so the bolts fall.

I have purchased a few of these and continue to do so. The price is affordable and they work. I do feel they fall apart easy but the magnet is the best around. Well, stronger than the other trays. And i mean in the heat and just throwing around. For the price, magnet and convenience (storage wise) i would give them a 5 but since the plastic does break after abuse or being in the heat too long, it makes them useless once that happens. So for reliability of that for any mobile guys or tool abuser, be gentle and cover them and they are great. Otherwise, buy a lot. I do wish the internal magnet was stronger but the bottom portion of the magnet is great.

These are great for holding nuts and bolts when working on cars or anything else. Magnets are strong. I use them for small tool storage in my tool box as well.

These are great. Stick them on my tool cart when not using them. Perfect when working on something that has lots of nuts and bolts

Magnets could be stronger. I have them flat on 4 corners of my lift and a slight nudge when empty falls right off. With lug nuts or weight in them, they are fine.

Love these things! I use them for work everyday for work doing HVAC, helps keep track of all my screws so I don't damage membrane roofs, and when I'm done it folds up nicely making it easy to store in my tool bag. Pretty durable, only broke 1 over the years.
