Line a baking sheet with parchment paper.
Spread the pretzel sticks evenly across the lined baking sheet.
In a microwave-safe bowl, melt the white chocolate chips in 30-second intervals, stirring in between until smooth.
Drizzle the melted white chocolate over the pretzel sticks, ensuring they are well coated.
In separate bowls, melt the red and blue candy melts using the same microwave method as the white chocolate.
Drizzle the melted red and blue candy melts over the pretzel sticks in a decorative pattern.
Immediately sprinkle the red, white, and blue sprinkles over the top while the chocolate is still wet.
Place the baking sheet in the refrigerator for about 30 minutes to allow the chocolate to set.
Once set, break the pretzel bark into pieces and serve.
