Vintage White Castle Restaurant Coffee Mug Heavy Duty 10oz

Vintage White Castle Restaurant Coffee Mug. White, Heavy Duty, 10oz. Apparently this mug had an "ashtray" style bottom and can double as one too🤔 Great for the mug collector or a White Castle fan. No chips. Every mug manufactured like this is different. Little black specs can be seen in the finish. Unique style! Measurements: 3 inches tall, 2 inches wide. Message me if you have any questions. I'm happy to help.
