Collapsible content
Are ceramic mugs microwave and dishwasher safe?
Yes, most ceramic mugs are both microwave and dishwasher safe — especially if they’re glazed and properly fired. All of our mugs are made with durable ceramic and finished with a high-quality glaze, making them safe to use in the microwave and dishwasher daily. No fading or cracking with regular use.
What size are standard coffee mugs?
The most common mug size is around 330 ml (11 oz), which comfortably fits a standard cup of coffee or tea. We use this size because it's versatile — big enough for your morning brew, but not oversized. If you're after something larger, we also offer 15 oz options in select designs.
Do ceramic mugs keep drinks hot?
Ceramic mugs retain heat well, especially compared to plastic or paper cups. While they don't insulate like thermoses, ceramic holds warmth for a good amount of time — making them ideal for enjoying coffee, tea, or cocoa at home or the office.
Will the design on my mug fade or wash off?
Nope! We use high-quality printing techniques that fuse the design into the surface of the mug. The result? Long-lasting prints that won’t fade, peel, or scratch — even after hundreds of dishwasher cycles. You can enjoy your favorite design for years to come.
Are your mugs safe and eco-friendly?
Yes. Our mugs are made from non-toxic, food-grade ceramic and are free from lead and BPA. Plus, they're reusable — helping reduce waste from disposable cups. They're also produced in the EU under responsible manufacturing standards.
