Personalized Refrigerator Magnet, Custom Children’s Art Magnet This is a wonderful custom present for grandparents or just a nice addition to your fridge to display children's art. If your fridge is anything like mine then it's always covered with awesome art brought home from school! Give your kid their personalized, custom magnet so they know you appreciate what they made! Custom Magnet is made from 1/8" Baltic Birch plywood. These are made to order so please allow enough time (2-5 business days for me to make it). Magnet is approx. 3.5" wide (approx 9 cm).
