Please note that these vases are produced in Mexico by our glass factory. These vases are produced using recycled glassware and the quality will be slightly different from that of our normal Chinese hand blown vases. These vases will have a slight green tint, slight bubbling in the vase walls, and will have a lump at the rounded edges where the glass is cut to form the top. These vases are used mostly by florists and designers who intend to arrange them with flowers and decor within the vase so that most of the bubbles or color difference is minimized.
