Trading Card Case Hard Case Deco Trading Card Case Deco Whip Deco Keyholder I received this as a gift, so I don't know the exact size, but it's slightly smaller than B8, with internal dimensions of 57 x 90 mm. It was a size that allowed a popcorn sleeve to fit with a little room to spare. I checked after taking the photos, and the heart-shaped hologram in the first image was the sleeve that came with it. The hard case itself does not include a hologram. Please check the second and third images for more detailed information. I have stored it in a dark place since receiving it. I will sell it because I have no opportunity to use it. Instant purchase OK I will also consider price reductions. Please feel free to ask if you have any questions.＾＾
