A Showa-era glass "ishikeri" (a type of glass marble). It has an embossed "Hyottoko" (a comical Japanese character) on the surface. There is a small chip on one side (please see the last photo). Other than that, I think it's in good condition. Please check the photos for other details of the condition and size. Please also read and agree to the contents of the profile section. We are looking forward to your purchase.
