According to INSIDER, Hershey's plans to debut a new Reese's cup in the spring of 2019. The new candy will be called Reese's Thins, and it will be approximately 40 percent thinner than the original. "[Reese's Thins] appeal to those consumers who want something sweet with more permissibility," Hershey North America president Michele G. Buck reportedly said on a call with the company's investors on Thursday.
