MaxGear Magnetic Marker Holder, Acrylic Pen Holder for Fridge 2 Compartments, Dry Erase Marker Holder with Screws, Clear

This exactly what I needed for my classroom - room for 6 markers plus an eraser and clings right to the board so the markers are all in one place and not all over the railing. And, can be pushed up to the top of the board, out of reach of little hands.

Teachers love it very sturdy

Works as described.

Easy, sturdy and holds more than just a few markers.

I put this in my office at work! Now everyone wants one! My bad boss.

Magnet is strong enough to hold on a marker board when full

This is exactly what I was looking for except it is on the smaller side. However, the divider piece in the middle can slide out making it one big compartment. Overall I am satisfied with this purchase.

Very simple, nice design. Clear acrylic is great to make it "disappear" or look visually "lighter", as logn as you don't mind seeing the contents of the holder. In this case, we did not want a clunky dark plastic container. It is also nice that you can remove the center divider for more flexibility. Note that acrylic can be scratched and it can also attract lint/look dusty.

A little smaller than expected but love the thick acrylic. It has a strong magnet, too!

This product is not "adjustable." You can remove the divider, however you cannot adjust the size of the compartments. The magnet is however very strong.
