Line a baking sheet with parchment paper.
In a microwave-safe bowl, melt the white chocolate chips in 30-second intervals, stirring in between, until smooth.
Dip each pretzel rod into the melted white chocolate, allowing excess to drip off.
Immediately sprinkle red and blue sprinkles over the chocolate-covered pretzels. Place them on the prepared baking sheet.
In another microwave-safe bowl, melt the milk chocolate chips in the same manner as the white chocolate.
Drizzle the melted milk chocolate over the pretzels using a fork or a piping bag for a decorative effect.
Allow the pretzels to set at room temperature for about 30 minutes, or until the chocolate hardens.
