11 oz hand pressed mugs are microwave safe. Each mug is heat pressed for a long-lasting finish and come with aftercare instruction! 

• An incredible choice for coffee, soup, tea, milk, latte, hot cocoa and more
• There’s plenty of room between the handle and cup itself, with the well-shade handle, so comfortable in the hand that makes your beverage even better.

I pay very close attention to each detail of my products from hand making them to the packing and shipping. Keep in mind there could be small imperfection and shipping time is 7-10 days
