True Brass Thimbles - for Rope/Cord/Paracord. Not that gold plated nonsense, and quite possibly the only place on the internet to find them.
As previously sold by Martin Combs: the first size is the size of the Groove for rope/cord to sit in, and the second size is the overall length of the thimble.
