Looks can be deceiving! No matter how many times I took this picture it looks like a round bead. Or Double Bubble! It is actually 15mm tall and 17mm around the outside. A gorgeous soft pink matte with hole running from top to bottom.
Have had this vintage Japanese bead tucked away for years and for some reason thought they were glass. They have the weight and look of glass but they are 6mm square with a white old acrylic base and a terrific red coating.
