Mystery object.
While helping to clean out my Grandparents office I found this mystery item.
I was curious if anyone on here might know what it is or what it was used for. Found amongst the stationary.
Thank you for your help!
UPDATE: Thank you to all who responded and helped solve this mystery. I've never come across a cord grommet like this, but now that I know what it is, I can put it to good use. ^^ so thank you!
