Great design for water
"It’s too bad because I really do love the designs and was looking forward to using for teas. I was avoiding teas that would stain and went the herbal route (spearmint, lemon ginger, chamomile) and not sure if some kind of reaction happened with the glaze as the texture became rough inside. I emailed Tammy for a solution end of July and she did say she would replace; however it’s now September and have yet to get a replacement. If you buy then be careful as they do stain easily (used another cup I bought for other teas such as Jasmine). Or you can use it for water as the glaze has not come off with that thankfully."
