In small microwaveable bowl, microwave white chocolate molding wafers uncovered on Medium-High for 15 to 30 seconds. Stir. Continue in 15 to 30 second intervals, stirring each time until all the wafers are fully melted. The wafers will retain their shape until they are stirred; use fork to dip balls into coating, tapping any excess off. Place on parchment-lined baking sheet to harden.
