Old glass marbles. The number "10" is embossed on the surface. It has a bumpy, luster-like surface. It may be one of the older marbles. There is a large indentation on the bottom, but it is unclear whether it is a chip or from the time of manufacture (see the last photo). There are small scratches and dirt overall. Please check the photos for other detailed conditions and size. Please read and agree to the contents of the profile section. We look forward to your purchase.
