Lifeproof for iPhone 6/6s PLUS EUC

I bought the case and decided I'll never use it. I LOST THE HEADPHONE ADAPTOR. you can buy it for really cheap online. Also, there is the faintest marks from my monogram on it. You can most likely clean it off or absolutely cover it with another monogram/sticker. No scratches on the screen, 1 minor minor scratch on the top. I never registered it for the warranty online, so I'm included that card and the box. Bought for $100
