Twitzels was a pretzel manufactured by Perfect Foods, Inc. My 84-yr-old mom remembers them. They are mentioned in this article as the company once made spiced snaps cookies, https://www.inquirer.com/food/sweetzels-spiced-wafers-ivins-cookies-acme-fall-philadelphia-20190925.html. I found the address through Pennsylvania Business Search. There is an empty Twitzels' tin can on eBay. Curiously, there is a pretzel company in Korea called Twitzels.
