Thank you for viewing. This is a set of two Italian-made heat-resistant glass bowls (large and small) from Shimada Special Glass Sales. Although unused, they are old and have deteriorated over time. They are generally dirty. Size (Large) Diameter: Approximately 23cm Height: Approximately 9cm Capacity: Approximately 2L (Small) Diameter: Approximately 17.0cm Height: Approximately 6.5cm Photo ⑤ compares them with a 500ml plastic bottle; I hope this is helpful. ☆ Although you can pour boiling water into them, do not put them directly on a fire. ☆ Do not put them in the oven. ☆ Do not subject them to sudden impacts, such as dropping them from a high place. ☆ Please refrain from price negotiations.
