Please note: These are vintage, preworn and/or preloved items. I do my utmost best to list any issues, but signs of wear should be expected, and there are occasionally small things I won't deem worthy of note. Please feel free to send me a missive with any questions. I'm truly happy to help in any way possible and I'm always up for a chat.
