Details:
Each comic comes with a self-adhesive plastic sleeve and a backboard for protection. I have no idea if the plastic is acid-free, so if you're a big time comic book nerd and care about that sort of thing, you might want to replace the plastic sleeve/backboard when you get it. If you don't know what I'm talking about, don't worry, it probably means you take showers regularly.
The comic has high quality glossy pages, it looks and feels a lot nicer than comics printed on matte or shitty news print. The front and back covers are in full color, black and white inside.
