Microwave white candy melts in a microwave-safe container at 50 percent power for one minute. Remove from the microwave and stir.
Continue microwaving at 50 percent power in 30-second intervals, stirring in between each set until completely smooth and melted.
Over a bowl, use a spoon to coat ¾ of each pretzel rod with the white candy melt.
Place on a baking sheet lined with foil or parchment paper.
Repeat steps 1 and 2 for the red and blue candy melts.
Pour the melted red and blue candy melts in separate small plastic storage bags, then clip off one corner of each bag to make a tiny hole. Tip: Place the plastic storage bags inside a mug and fold the top of the bag over the rim of the mug to make filling the bag easier.
Use your filled plastic bags to drizzle each pretzel with red and blue melted chocolate.
For sprinkle-covered pretzels, coat each pretzel rod with the white candy melt. Then, pour sprinkles over it while slowly rotating the rod. (Tip: Do this over a large bowl to collect and reuse the sprinkles that don’t stick.) Place on a lined baking sheet.
Leave all pretzels out in a cool room or refrigerate for at least 30 minutes before serving.
