** Most of my items are vintage or preloved.  I try my best to accurately describe or take pictures to show flaws or defects.  Please - if you need any additional information, I will be glad to help.  I do not smoke and am allergic to it, so I generally will not buy or sell anything that has this odor.  I will mention it if I do.  If you are not satisfied, please contact me as I want us both to have a pleasurable shopping experience and will work with you.  If you have any issues with your product, please contact me prior to leaving feedback and we will work it out!! Honesty of sellers and buyers is what makes EBAY a wonderful place to shop!!
