Thank you for viewing. This is a set of three Italian-made heat-resistant glass bowls from Shimada Special Glass Sales (all three are the same size). Although unused, they are old and show signs of aging, with small scratches, stains, and air bubbles as seen in photo ⑤. Photo ⑥ compares the size with a 500ml plastic bottle. Size: Diameter: Approximately 17.0 cm Height: Approximately 6.5 cm ☆ You can pour hot water into them, but do not put them directly on a fire. ☆ Do not put them in the oven. ☆ Please refrain from price negotiations.
