Hi there! I’m back. I’m downsizing my collections, and what you see is what will be shipped. This Lanyard has never been used. Unfortunately, the “light up” feature doesn’t work. I don’t know if you can change the battery, but I haven’t tried. I will send a new, random anti-bac with it. I can’t really use them anymore, as they dry my skin out. So, I’m selling off my collection. The anti-bac holder will be shipped quickly and safely in a padded polymailer. *free Shipping if offered for ground ship, only. Thanks for looking!
