He sounds like a very smart man shiroaiko.
I used to toss aside Cateyes like they were rocks so Rick and I am on the same page.
Quart jars of these sell like fire at a rummage sale--at least back then. I remember my wife having great luck with selling these at our last rummage sale about 15 years ago--the trouble was, after I gave her what she wanted and they sold--she went back into my basement stash and started filling jars without me knowing it.
She picked the wrong buckets for sure--we are still married😁.
Marble--On!!
