❣️ Thank you for viewing! ❣️ Purchase without comments is welcome ☆彡 Brand new, unused item. Please check the images for the condition of the contents and outer box. ◇ Product Description Glasses that perfectly combine functionality and design. The double-walled glass with air in the middle layer acts as an effective insulation layer, preventing temperature changes in the contents due to the outside air. It prevents the temperature of the drink from changing due to the heat of the hand or the outside air. It is also difficult for hot drinks to feel hot to the touch, and cold drinks do not easily form condensation on the sides, maintaining the temperature. In addition, the hydrophobic silicone vent on the bottom allows only air to pass through without letting water through. By allowing air to pass through, whether you pour hot or cold drinks into the glass, it equalizes the pressure of the air between the double-walled glass and the outside, maintaining the stability of the product. ********** To those considering a purchase ********** 【About Purchase】 We are sorry, but we do not accept returns, so please check the photos and the description carefully before purchasing. 【About Shipping】 Rakuraku Mercari便 ⇆ Yuuyu Mercari便 ※ Please note that the shipping method may be changed.
