Manga Graphic Novel SLEEVES.
6-1/4 x 8-1/2" 2.5 mil Polyethylene.
1-1/2" flap.

Was looking for some bag sleeves for my A5 doujinshis and found that this work perfect for them. The thickest I got in was a 3/8".

I bought these for my standard size manga - Tokyopop, Viz, Del Rey's Shoujo line. These bags are too big for those. There is a great deal of wiggle room. However, I accidentally received one bag in my batch that was one size smaller, and that one is too small. So if you're looking for the size for most manga, this is your best bet. It also *just barely* fits some of the old style larger manga, if they're not very thick. (I'm talking the old style Viz, Pulp, Mixx, and Tokyopop, very early 2000s.) I'm not sure where I got the impression, but I somehow assumed that the flap would have adhesive on it. It does not, which I ended up being happy about, because 1 piece of scotch tape works great. Overall, these bags have a nice sturdy feel to them. The weight is just right. I wish they were a little more snug, but since the next size down won't fit the standard size manga, I'll be keeping these.

I bought these to protect my manga collection of "Monster".I accidentally got mine a size too big, but they work great nonetheless.
