Old glass marbles. There is a butterfly embossed on the surface. The surface has a warm-toned luster, and the base glass is blue. There are fine, dot-like flakes of luster on the surface. There are a few small flakes of luster on the sides (please see the last three photos). Other than that, there are no problems, and I think it can be said to be in generally good condition. Please check the photos for other detailed conditions and size. Please read and understand the contents of the profile section as well. We are looking forward to your purchase.
