This is one bromide. As shown by the circle in the second image, there is a slight warp when held up to the light. Please check the images and only purchase if you are not concerned. It has been opened to check the contents, but it is unused. I am selling it because I will not be using it. It has been stored in a clear pocket, but as it is from several years ago, there may be signs of aging or warping. Please understand this. It will be shipped with water damage protection and reinforcement on both sides. Please refrain from purchasing if you are nervous about storage, as it is stored by an amateur. Also, please refrain from purchasing if you are concerned about initial scratches. Please check my profile before purchasing. Instant purchase is available. Thank you. ufotablecafe
