Has anyone ever used a security tag when you sold your LVs? I purchased an LV on eBay once and there was a "security tag" attached to it, the material felt like tyvek and once it was ripped, it couldn't be attached. I'm selling two of my speedies on eBay so I can get them in a bigger size and I was wondering where I can get those tags? What are they exactly called, does anyone know? I don't want to experience a "bait and switch" with any buyer. Any help would be greatly appreciated. Thanks!!
