The flower holding the note and the back of the dispenser flap is magentic. The flower is cut from the Fun Flowers Bigz Die.
I've used the two magentic sheets before in a 12 days of Christmas magentic stocking from the Adorned Holiday Sampler.
While both the top flap of the dispenser and the flower are magnetized, it seems to slip, probably due to the sheet of designer paper covering the magnet. It might be worth the time to attach a heavier magnet to the back of the flower to make sure it doesn't slip unexpectedly.
To modify the template from a candy dispenser into an office dispenser, I simply inserted a 2" x 1 3/4" box in the rear of the base.
