I hear your frustration. I would also just refund the sales price only & tell him to keep the marbles.
At that point if you get a negative you can respond w full refund was issued. No-one will hold that against you.
Some Ebay buyers you cannot make happy no matter what you do.

I feel your work has a very unique flare with lots of forethought.
I think many board members are nervous to post due to the recent
HOT Topics, LOL
Thanks for Sharing Bo.

A great deal of the overall collectibles market has fallen apart.
When people are worried if they will not have a job tomorrow or how to just pay bills,
collectibles and sometime Marbles get put on the back burner.
A sign of the times...
