Samsung galaxy prime case w/ rose gold ring holdr

Case: Brand New, No flaws/Silicone/Black and white marble/Bought for Samsung galaxy prime j7. It fits the phone perfectly snug, but the buttons don't like up w/ the cut outs. So I believe it's for another Samsung galaxy prime model, but not sure which. Ring holder attachment: Brand New, In package/Square/Rose gold color w/ silver color ring part/Bought to go w/ case. I have another one and this thing is snug, doesn't move, sticks well.
