The bases on these vases are larger than the bubble vases having a circumference of approx. 200 mm (blue) and 190 mm (red). The stem is round where it joins the base, but has been flattened slightly at the top to form a triangle. Each vase is approx. 214 mm in height. I have also seen them with a green/white stem and a clear/white stem. Although these are often misattributed to Murano (including the use of self adhesive Murano labels), I believe these were made in Hong Kong as another of my vases has a worn but still readable label. The label is oval with a metalic gold background and lettering in black stating " Made in Hong Kong" (see images below).
