This is a vintage Antique handmade Glass Marble. This a Coreless transparent Swirl. The outer bands are blue and yellow with a few fine white lines (The colors are a bit darker than the photo). The size is about 5/8 of an inch. Good Vintage condition; no notable chips, just some light wear. Because my items are vintage/used they may have some signs of use/wear and/or be in need of some cleaning. I have not tried to clean or do anything to the piece. Will ship to United States ONLY. Buyers in PA will need to include 6% sales tax.
