Small Shelf (Magnetic)

This is a remake of a small shelf I designed to hold spices on my fridge, it has 4 slots for 60x10x3 magnets (https://amzn.to/3Q4Nmz9) to mount to any metal flat surface. I also attached a thin piece of rubber to the back to give it a little more grip and this thing is solid!  The bottom is also flat so it can sit on a desk or somewhere else as a holder.
