This is a vintage Antique handmade Glass Marble. This a Latticino Core Swirl. The core has white threads. The outer bands are blue,and pink (the flash washes out the colors so check out the darker photos done without a flash). The size is about 9/16 of an inch (just about a peewee size). Vintage condition; Lots of small bubbles inside. It has some rough spots small nicks. 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.
