Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper.
Spread the pretzel sticks evenly on the baking sheet in a single layer.
Bake the pretzels in the preheated oven for 5-7 minutes until they are warm and slightly crispy. Remove and let cool.
In a medium saucepan over low heat, combine the caramel bits and heavy cream. Stir continuously until the caramel is melted and smooth. Remove from heat.
Pour the melted caramel over the baked pretzels, using a spatula to spread it out evenly and coat the pretzels.
In a microwave-safe bowl, melt the semisweet chocolate chips in 30-second intervals, stirring between each interval until fully melted and smooth.
Drizzle the melted chocolate over the caramel-coated pretzels, covering them as evenly as possible.
Sprinkle a generous amount of sea salt over the chocolate while it's still warm.
Place the baking sheet in the refrigerator for about 30 minutes, or until the chocolate has set.
Once set, break the bark into pieces and serve or store in an airtight container.
