This is a set of two Butler Eez-Thru Floss. It has two functions in one: a green thread section for inserting into the gaps of bridges, crowns, implants, and orthodontic appliances, and a white floss section for cleaning under bridges, etc. I can't offer a significant discount, but I'm open to price negotiations♪ Although it's new and unused, please understand that it's stored at home and will be simply packaged. I look forward to your purchase ( * . .)"
