OUTXE 10-Pack Magnetic & Adhesive Pen Holder with Dual Slots - Easy Organize & Access Pencil, Pen, Marker- Perfect for Desk, Wall, Refrigerator, Whiteboard, Clipboard

The magnet is built into the holder. The holder attaches easily and holds tight to my refrigerator.

Item works well magnets are strong and they hold pencils they hold up

I love these. They are so practical and can come in handy in so many applications. This works great with the quantity received. The magnet is not extremely strong and the adhesive did not ensure the outside heatin my vehicle. It's March (Alabama) for reference. It's sure to get hotter. Still worked great for me.

Using at home and work. Magnet holds well. Not sure you could fit 2 in these.

Used these at work so that we have Sharpies wherever and whenever needed. Love the option for magnetic or sticky mounting. Securely holds a sharpie and it's easy to grab it and put it back.

I used thick rubber bands and super glue on the bottom because these will be handled by hundreds of people and need to be able to withstand abuse as well as the outdoor weather.

I love the usefulness of these pen holders. We have a metal door near our exit, and we require drivers to sign in and out. They will always be able to find a pen now. I also used mine on my metal filing cabinet. Nice strong magnet, so it won't fall off. I really like the flexibility of the soft durable material so that all sizes of pens, pencils, markers, and highlighters will fit nicely.

Good magnet strength. It fits smaller pens better. Larger/ normal sized white board pens fit, but just.
