These are Duralex gradient glasses that were sold exclusively when the Ron Herman Sendagaya store was renovated on June 18, 2011. I bought these glasses after waiting in line for hours on the opening day. They are quite rare and sold out quickly. There were several colors, but I found this color particularly beautiful and bought several glasses. I had them in stock for personal use, but my tastes have changed over time, so I am now selling them all together. Only one glass was opened for the photo shoot; the others are still wrapped in bubble wrap as they were when purchased. They have been stored in my home's kitchen cabinet. * It appears the color is applied over the glass, so there are inevitably some spots where the color is missing due to individual differences. * New, unused, and unopened items. * Not sold individually. * Please feel free to ask any questions.
