Glass Coffee Cup adopts a double-walled glass wall design. Each glass cup is hand-blown. There are air holes left during the blowing process at the bottom. Please note that this is not a defective product. Each air hole is blocked with sealant. Live, so you need to take more care of the cup during use. Please do not use the dishwasher and microwave during the cleaning process. Just clean it after use. The double-layer insulated glass can withstand sudden changes in temperature. The temperature range is from -22℉ to 302℉, even after filling with ice water. It will not break easily even if it is filled with hot water. This high borosilicate glass is lead and BPA free, so you can use it with confidence. Even if it breaks, because of the different materials, this kind of glass will not break into small pieces like ordinary glass, but into large pieces of glass, which protects people's safety to the greatest extent.
