prinkles do have expiration dates. The exact shelf life of sprinkles can vary depending on the type and brand of sprinkles, as well as how you store the sprinkles. Most manufacturers recommend using sprinkles within  a year or two years of the production date.  Some sprinkles may have a shorter shelf life. To ensure the best quality and flavor, it's important to store sprinkles in a cool, dry place, away from sunlight and heat. Exposure to moisture or heat can cause sprinkles to clump together or lose their color and texture.  If you’re unsure, smell the sprinkles and taste them. If they’ve gotten stale, the flavor may taste off.
