The GamersNexus Mule Mug is a stainless steel, copper-plated mug with a laser-etched thermal conductivity formula on the outside. The mug’s surface is a hammered finish to give a brilliant interaction with light and some extra texturing. The mule mug is truly unique and is a perfect match for viewers familiar with GN’s in-depth thermal testing, while also providing a mug with a great look on your desk. The stainless steel inner lining combined with the copper plated exterior helps the drink to “feel” colder and is a long-standing vessel of choice for certain drinks.

These mugs are great for cool drinks on a warm day with a bit of nerdy flair. The formula presented is an approximation for the thermal conductivity of copper (depending on thickness and temperature tested). These are ~17 oz. mugs.

Caring for the Mule Mug

• Hand-wash the mule mug after use. The mule mug is not dishwasher safe and finish should be protected by hand-washing the mug. Use cool water to wash.

• Do not microwave the mule mug. The GN mule mug is not microwave-safe.

• DO NOT USE THESE MULE MUGS WITH HOT LIQUID. THESE ARE THERMALLY CONDUCTIVE (copper + stainless steel) AND MAY CAUSE BURNS. USE ONLY WITH COOL DRINKS.

• These mugs will last a long time if following the above care instructions.

• Includes a 1-year warranty with the same guidelines as our GN15 glassware (exception of the metal emblem)
