This is a high-end rock glass designed by product designer Fumio Sasa. The second photo shows Mr. Sasa's engraved signature on the bottom of the glass. This is a top-of-the-line product from HOYA Crystal, made with the finest crystal glass and featuring intricate and bold cuts. Made of very thick glass, the actual product has a more luxurious feel, presence, and weight than the photos suggest. It sparkles brilliantly when held up to the light. HOYA ended its crystal business in 2009, making this a very rare item, as it is only available in existing glasses. You may not come across one in such good condition again. There are no plans for a significant price reduction in the future. The price may increase depending on circumstances. This is a truly wonderful piece, so please consider purchasing it as soon as possible. Size: Diameter approx. 85mm, Height approx. 100mm Accessories: Original box, cloth, and leaflet The glass is a masterpiece that retains its original luster and beauty. However, the accessories show signs of aging. The original box has deteriorated and has some stains due to age. This item has been stored at home for a long time, so there may be minor scratches or stains that I have not noticed. Please refrain from purchasing if you cannot tolerate even the slightest scratch, if you are looking for a new item as if purchased from a store, or if you do not understand used items. Please note that recycled packaging materials may be used. Returns and refunds are not possible due to the nature of the product. Please consider purchasing with your understanding.
