Hey Guys,
Found this website and am ordering a case from them. A little pricey, but MADE IN THE USA!
They are putting 1″ layers of 2# foam that i can cutout to fit the profile of what i want. They are gluing 1/2″ foam on top and bottom. Plan on using plexiglass to seperate stones into 2 levels with foam glued to the plexiglass. Hope this makes sense to those who read it!
