Normally I wouldn't either, but after finally using up the candle that was inside when I bought it, I couldn't wait to clean up my new teacup and use it! But … the cup doesn't have a backstamp on the bottom, and that makes me a little nervous. Is this food safe? I don't know, so I emailed the company (whose name I found because I blogged about the teacup when I bought it last year), and I hope they'll write back and tell me my teacup is safe to use. If not … I guess I have a pretty new paper clip holder!
