Magnetic Pencil Holder & Mesh Storage Basket - Metal Organizer with Strong Magnets for Whiteboard, Fridge, Locker - Perfect for Office, Kitchen & School Organization (Black, 2-Pack)

Got these to attach to a metal three tiered, wheeled trolley cart I use for crafting. I intended to stick these on the outside of the metal bins, but as I filled the cups, they were sliding down. I felt better attaching them on the inside of the bins so they'd stick securely, but hate the loss of the space inside my three cart bins where I could be putting other crafting items.They're useful enough, just would prefer stronger magnetic adhesion.Since I work from home now, my little desk does not have a ton of desk space. So I had to consider alternate options. I came across this and huzzah! I got the idea that I could put my pens and such in these and attach to my file cabinet next to me.Perfect. Accessible but not in the way. I am going to be perusing more magnetic desk accessories!I wasn't expecting four smallish magnetic pencil/pen holders (I know, read the reviews), BUT turns out I have one on my garage fridge, one on my kitchen fridge, and two on the vertical paper holder on my desk. They hold to all surfaces mentioned and are extremely useful for several pens and extra reading glasses. I'm happy with the purchase.Only wish it would have a stronger magnet. It slides down from just holding 5 pens. Maybe because when I close my locker the vibration makes it slide down a little at a time.These worked perfectly for my white boards at home. The only thing is that the magnets are SUPER weak. I will need to replace them with normal magnets, but for the price is right.My office has metal shelving for books and file boxes, and we needed easy access to pencils. These pencil holders work perfectly. They don't stick out too far and the magnets adhere to the metal just fine. It's great to keep writing utensils close by when we need to update files.I bought these for my locker at work. Amazing. Holds my work junk and stays put inside the locker.The magnets on the back on just under the mark when it comes to strength. I would like to seem them at least double as a strong.
