Frequently Asked Questions
Does the 12oz coffee cup come with a lid?
Yes, it does. All of our 12oz coffee cup models—glass, plastic, and insulated stainless steel—come with a plastic press-on splashproof lid.
Can I use the 12oz coffee cup in the microwave?
Yes, you can heat your 12oz glass or plastic coffee cup in the microwave to 100°C - make sure you remove your lid first, as these are not microwave-safe.
You cannot microwave a 12oz stainless steel coffee cup - these are not microwave-safe.
How should I care for my 12oz reusable coffee cup to extend its lifespan?
While all KeepCup reusable coffee cups are dishwasher safe, handwashing can help extend the lifespan of your 12oz cup. Use mild soap and some warm water to clean your cup—don’t use harsh chemicals or abrasive cleaners, as they may damage the finished surface. Let your cup air dry for the best results. You can read more about cleaning your KeepCup on our care page.
Are there different designs or colours available for the 12oz coffee cup?
There are! In the 12 oz size, you can choose between tempered glass, lightweight plastic, or insulated steel coffee cups. You can also choose from press-on lids in a range of colour combinations, creating a 12oz reusable coffee cup that speaks to your personal style.
Are replacement lids available for purchase?
Absolutely! We've got you covered with replacement lids and all other parts you might need. This allows you to replace only the parts you need – not the entire cup – supporting our commitment to sustainability and long-term use.
