These were among some of my first jewelry displays purchased in

the early 80s when I was doing clients visuals in around Harrisburg. 
No damage  but I can see that one  base has some clear marks that look like minor scratches but there is no roughness so thinking  it was flawed acrylic from the onset on this one.  Really not noticeable in use.

Selling them as a group of three for this great price whic include consideration of the minor marks on the one base.
