I've never used a cookie press before, but I found this one at a thrift shop and plan to use it soon. I'm unable to find the manual for this specific one as it's ancient apparently. I think I was able to figure out how to put the discs in (hopefully) correctly, but what are the metal piece on the front and the hershey kiss on the bottom for? Also anything I need to know about cookie presses feel free to share:)
