Description

Key Rings, Birthday Themed, Huge Lot 500 plus
Every month is accounted for.  Missing some days for each month. Some days there are anywhere from two to seven of the same day.
These came from a store that is no longer in business/unsold stock. Key rings were taken off shelf, boxed up, and put into storage for a while.
Most still have original barcode tag (original packaging?).
The plastic tag part does come apart. The little card inside can be removed and replaced with ??? Then snapped back together.
Few might have a little bit of tag smudge. Pulled out as many of those I could find with tag smudges, but might be a couple few/some I missed.
Used/Not Used?
Only two options to choose from, new or used.
As far as these key rings being used for what they were made for... to hold keys, no they have not been used.
Handling to sort, organize, go through looking for damaged ones, storing them, and... are they considered used?
Thinking these would be great for craft projects. The frame/card holder/???? snaps open and closed. Make your own personal/business card to replace the birthday date card.
