Designed to be used with the Maker's Board, this Colorful Magnet set is made from plastic-free PLA (plant fiber) and very strong magnets, strong enough that both the front and back will work.  It includes 6 discs with embedded magnets that can hold patterns, charts, or recipes on the Maker’s Board, or use them for artwork and notes on the fridge or a metal message board!  The PLA is formed around the magnets, no toxic glue was used to secure them and they won’t come out!
