Asian Color Ground Glass Joints - 14/20 - Female - Purple

When ordering ground glass joints you must consider measurements (X/Y=) Where X is the Top Outer Diameter, and Y is the Length of the Grind. (So 10/18 would be a Top Outer Diameter of 10mm and a grind length of 18mm) This item is sold by the end, so EA and 100pc both mean the number of joints you get, however this item is double ended.
