I have just resold a pair of new unworn Alden Cordovan by JCrew boots on ebay. The buyer won them for a price better than they would have got directly from JCrew. But now they are coming back complaining of imperfections, such as a string coming from a seam. As these are new in box, any imperfections would have been shown in the giant pictures I posted and are part of the deal. Am I right? Please advise.
