Trick or Treat? How about both this Halloween? Enjoy the mischievous side of Original SOUR PATCH KIDS Candy and SOUR PATCH KIDS Watermelon yourself or hand out as trick or treat bags. This Halloween candy package contains 40 individually wrapped trick or treat–size bags. Sour. Sweet. Gone! SOUR PATCH KIDS Halloween candies start out sour, but always end up sweet and sometimes even watermelon flavored. Soft, chewy, and oh so fun!
