These are hand painted directly on a very large, 25oz. glass beer mugs with layers of paint giving attention to detail to bring out the character of the person on the mug. This product is fired up (literally) to allow the paint to set on the glass. A process that is well worth the finished look!
This product is best maintained by hand washing with the soft side of the sponge, no hard bristles. Yes, you can drink out of them. Just remember to drink responsibly.
