**INSULATED COFFEE MUG** - The PARACITY double-wall glass coffee mug features a silicone lid that helps maintain the warmth of your beverage for up to two hours, allowing you to savor your coffee at a relaxed pace. This mug is crafted with double-layer glass, where air is trapped between the two layers. This design effectively reduces heat transfer, ensuring that your hands remain cool while enjoying your drink.
【SAFE VENT HOLE】The double wall glass has a pinhead-sized hole somewhere in the glass. These holes will not let water/steam/condensation water enter, which can well reduce the glass bursting during use. Water and air can only be expelled, not entered. They will be completely hermetically sealed. Therefore, our double wall glass coffee mug has high safety and long service life.
【SEAL LID】The insulated coffee mug is equipped with a silicone inner plug made of maternal and child grade material, which is effective in heat preservation and leak-proof, and the water will not leak out easily. Since the sealing inner plug is detachable, it is very easy to be cleaned. But pay attention, there is an air hole on the top of the lid, please do not turn the cup completely upside down.
【HIGH BOROSILICATE GLASS MATERIAL】The coffee cup is made of heat-resistant lead-free borosilicate glass, which is healthy and environmentally friendly, and does not contain any harmful substances.
