I find great joy knowing that all people will reap what they sow, and that all people will get to deal with God for their actions good or bad. If the item is listed as used or vintage please don’t expect a new or like new item. Most items will need a quick cleaning. I test them, & or inspect them, when I can & note what I notice in testing & inspecting. I have no idea if they will last 10 minutes or 50 years, no warranties are implied & no warranties are included. We sell a wide variety of used items. We try to describe them as best we can but we are not professionals, nor are we experts on any type of items we sell. Most of the items we sell are used. When we sell a used item normal wear, scratches, & signs of use should be expected. You are welcomed to come by & pick it up if you live close enough. I answer all emails.
