Nothing makes a child more proud then when you display their artwork on the refrigerator! I mean, isn't that why there's so much magnetic space on there?? These magnets can be for them so they can proudly hang their master pieces! They are 2.5 x .75 x 2.5, made of neon green rubber and have a nice square magnet on the back. Note: One magnet has an exclamation point, other does not. If you have a preference let me know.
