How did I know not know about TeaBloom!
I purchased the 12oz Legacy Glass Teacups (they are really mugs) and the Universal Tea Infuser. I have been looking forever for quality borosilicate mugs that are chemical free and that won’t break or chip after a few uses. These mugs are it. They are perfect. Finally, a company that cares about its products. I’ve already picked out tea and more mugs to purchase. They have a customer for life!
