Welcome to that's so Andrew! Let me tell you a little about our mugs! Material: 100% porcelain. Lettering: etched in (decal free). Capacity: ~14 ounces. Microwave & dishwasher safe? yes. Glazed: on the outside with white and on the inside with white or the pictured color. Our mugs feature a wide variety of quotes and prints that we are proud to design in-house! We occasionally collab with local designers and influencers, too! The fonts featured on most of our mugs is a custom font I created on my iPad using my handwriting and is unique to us. The shape & handle (which is quite comfy!) I created a pottery wheel in ceramics class and sent it over for mass production!
