Specifications

• Engraved Not Printed >> We use laser engraving machine to etch patterns or text into the mug's surface, making it feel more upscale compared to regular printed mug. Whether for personal use or as a gift, this mug will make you stand out.
• Larger Capacity >> The common 11oz coffee mug was considered slightly small. Therefore, starting from December 1, 2024, we will use larger mugs with an increased capacity of 1.5oz.
• Dishwasher&Microwave safe >> The pattern is directly etched onto the ceramic surface, without the use of any coatings or paints. This makes it truly dishwasher and microwave safe. With this mug, you no longer have to worry about the pattern fading or wearing off on your carefully selected personal or gift mug during use.
• Cobalt Blue&White >> The magical cobalt blue exterior exhibits subtle color variations under different lighting intensities, which is why it has long been regarded as a symbol of nobility, elegance, and mystery. The white interior makes it easier to discern whether the mug has been thoroughly cleaned.
• Shockproof Paper Box >> Your mug wraps in a professional shockproof Box to ensure it arrive in good condition instead of bubble film or just a paper box.
