PLEASE NOTE: Choking Hazard. This product contains small parts. Keep away from children under 3 years old. Adult supervision recommended.

These magnets will not work on glass magnet boards. They letters are made of a soft foam material and therefore are not impervious to imperfections, such as dents, or warping. However, these imperfections can usually be worked out with your fingers or a little low heat and easily reshaped on a magnetic surface.
