Enjoy your favorite tea in style with this beautiful glass mug. Its double-walled design doesn't just look elegant; it provides excellent insulation, keeping your beverages hot or cold for longer. The clear glass showcases an elegant luna moth design, adding a touch of natural beauty to your tea ritual. This mug includes a clear quartz crystal tea infuser, perfect for steeping loose leaf tea. The infuser allows the tea leaves to unfurl naturally, releasing their full flavor and aroma, while subtly infusing your water with the purported soothing energy of clear quartz. To ensure optimal enjoyment and longevity, pre-warm the glass mug with warm water before adding hot water. This helps prevent cracking. Sudden changes in temperature should be avoided to preserve the integrity of the double-walled glass.
