The original cat's eye road stud was not the glass type, this was the original invented by Percy Shaw, my old boss actually new him, this was invented in 1935.
I was installing road studs in the UK for many years, the glass studs used were not as deep as those installed here, but I suppose you could still trip over.
Has one of your relatives recently passed away ?
You don’t have to miss them you you can have them with you forever to remember the good times and continue to see their smile
Why not have them mounted into a really unusual coffee table
Also makes a fabulous talking point with guests over a nice pot of tea 😁😁
