Set of 5 beautiful glass bowls, perfect for dipping sauces. Size: Diameter 11 cm, Height 6 cm Base diameter 6.5 cm Glass thickness 4 mm These high-quality bowls feature a rugged design reminiscent of a rocky mountain surface, and are likely glass tableware from Sasaki Glass Co., Ltd. They are a Japanese glass tableware manufacturer with over 140 years of history. The outside of the bowls has a slightly uneven, rough texture and is semi-transparent. The inside is smooth. They can be used for a variety of things, such as salads, fruits, and desserts. Because they are deep, they can be used with confidence as dipping bowls for soba, udon, tsukemen, or for sauces and dressings. They have a Showa retro feel, but are clean with no cracks or chips. They are thick and sturdy, so they are unlikely to break even if dropped. I think they can be used for various purposes, such as small bowls. They can be stacked for storage, so they don't take up much space. (Photo 4) Two were stored in a cupboard and three were stored in a box at my parents' house. Therefore, I think two have been used, but three are unused. Please understand that these items have been stored at my parents' home, and please purchase them accordingly. These versatile glass bowls, why not give them a try?
