Quoted from PinballAir:
Aren't there chocolates that are the same size as those old condom boxes.
Fwiw; a guy "tomcat" on eBay was selling condoms from bygone times.
Not found any choc pacs yet. Apparently the pack dimensions for this machine were quite independent of other condom vendors of the time. I have purchased a couple of motors off tomcat so I will follow up with him. Thks.
