This is a set of key chain hardware parts. Perfect for handmade projects or replacing parts. The ring diameter is approximately 23mm. These were left over in my parents' storage shed. They have been opened, but the contents are all unused. Please note that there may be some variation in the number of pieces due to the fact that they have been opened. After confirming payment, I will wrap them in cushioning material and ship them via standard mail. If you would like to purchase individual pieces, please state your desired price in the comments section.
