When acquiring pre-owned, vintage, or antique items, it is essential to be aware of their condition. Certain items may be dusty due to the potential harm that cleaning could cause, and crazing may occur due to aging. I provide lots of photos & descriptions to the best of my ability, but I am not an expert. Please examine the photos and contact me with any questions prior to purchasing to ensure your satisfaction with the item. Returns are a hassle for both parties and are best avoided.
