Before First Use

• The lid is designed to fit tightly to help prevent spills.
• To make initial sealing easier, run the lid under warm water before use.
• Place the lid on the mug and press firmly around the entire rim until fully sealed

Microwave Reheating

1. To prevent pressure build-up, open (but do not remove) the small steam vent by pressing the widest part of the valve before microwaving the sealed mug
2. Microwave at MAX 650W
3. If heating for more than 2 minutes, stop and stir for even heating
4. Replace the lid, then continue reheating in 1-minute intervals as needed

After Heating

• Carefully remove the mug and let it rest on the countertop for a few minutes so heat distributes evenly
• Always remove the lid away from you, ensuring the steam is not directed toward you
• Use the built-in handle to grip safely when enjoying your meal

Important Safety Tips

• Fill the mug no higher than 2 cm (3/4") below the rim
• Always place the mug at least 5 cm / 2 inches away from microwave walls or door
• Avoid overheating small portions or foods high in fat or sugar (such as gravy, syrups, bacon, or bone-in meats)
• Check foods like gravy, syrups, bacon, or bone-in meats every 30 seconds after the first minute to prevent overheating
• Overheating can cause food temperatures to exceed 248°F (120°C) and may damage the container

Use & Care Guidelines

• Dishwasher safe
• Do not use sharp or metal utensils
• Not freezer safe

Not safe for oven or broiler use
