[Specifications] Capacity: 350ml, Heat-resistant temperature: -20℃ to 150℃, Size: Height 12cm, Top diameter 9cm, Bottom diameter 6cm [Double Wall & Heat Resistant] The double wall construction and heat-resistant glass material provide insulation, preventing the cup surface from getting hot and burning your hands. The cup's design keeps hot or cold drinks warm. [Less likely to condense] The double structure prevents the outside from getting cold and condensation from forming, so no coaster is needed. [Air hole at the bottom] Double-walled glasses are made of two glass pieces, an inner glass and an outer glass, and this hole is a necessary seal with silicone to allow air to escape when welding. Please note that this does not affect the quality of the product. [Please note] Because these glasses are handmade by artisans, slight distortions around the rim, warping of the glass, and small bubbles may occur due to the manufacturing process. Please understand that these are product characteristics. Improper handling may cause damage during transportation. [After-sales service] If you have any problems or issues with the product, please feel free to contact us and we will do our best to resolve the issue.
