'Marrying' is a jewelry store in Germany that's not letting men avoid popping the question any longer with the excuse that they don't know their wife-to-be's ring size. To encourage more proposals and ring sales, Marrying had a Ring Stick created from a business card.
The Ring Stick was devised for Marrying by the Jung von Matt/Alster Hamburg and the small ring sizer is designed with one small adhesive corner, so that it keeps its shape when rolled and there's no discrepancy in ring size. Since The Ring Stick is designed like a business card, it's pretty covert and all a guy would need to do is slip a ring onto it to determine the right ring size. If you're planning a surprise engagement, this is one tool that's extremely handy to have.
