Although I do try to accurately describe items and make note of imperfections, I can make mistakes or overlook things.  But, if you receive an item and I have provided inaccurate information about it, please let me know so I can make it right.  Also, I specialize in vintage items so patina and age-related wear may be present.  Again, please examine photos carefully and feel free to ask me questions.
