Review on 🧲 High-Quality Adhesive Magnetic Sheets (12 Pack) - Easy Peel & Stick, Flexible 8 1/2" X 11 by Kelly Caballes

Although these magnetic sheets are not designed to hold heavy objects, they are ideal for holding dies. They're pretty flexible, so I line them with chipboard (I buy thick chipboard, but you might as well trim the front and back of the cereal boxes to fit) and store them in folders in a protective sleeve. I put big hard stamps on them and they stay in place even when the sheet is held upright. Perfect for my needs and much more economical than the 3 pack of magnetic air vent caps I bought at the hardware store.
