Not sure how they count to 100, but twice I got less than the 100 bags advertised. Other than that the product itself is fine, love the re-sealable band that others don't offer, so no need for tape.

Ich bin sehr zufrieden mit den Schutzhüllen von Ultimate Guard. Sie haben die perfekte Größe für meine Mangas und bieten einen hervorragenden Schutz vor Vergilbung. Die Qualität der Hüllen ist beeindruckend und sie sind robust genug, um meine Sammlung langfristig zu schützen.Die Hüllen sind klar und durchsichtig, sodass die Cover meiner Mangas gut sichtbar bleiben, während sie gleichzeitig vor Staub und Beschädigungen geschützt werden. Die Handhabung ist einfach und die Hüllen lassen sich problemlos öffnen und schließen, ohne die Mangas zu beschädigen.Insgesamt gebe ich diesen Manga-Bags 5 von 5 Sternen. Sie sind ideal für jeden Manga-Sammler, der seine wertvolle Sammlung in einwandfreiem Zustand halten möchte. Eine klare Empfehlung!

Excellente protection, parfaitement adaptée à tous types de mangas. Le produit est de très bonne qualité, je recommande fortement !

Très bien, je les ai acheté pour protégé des Dragon Ball edition pastel, un peu grand pour ce format de manga cela dit mais si l'idée est de les mettre sous vide et de les protéger ce produit est le bon pour vous

They work as the description says. I have purchase these twice & will continue purchasing them. Now these don't fit on every manga out there. They fit some specific manga size & I'll write a list of the manga I have these on & the ones I don't in hope of helping.The manga I have these on & fit are:A Silent Voice, Assassination Classroom, Bakuman, Berserk. Case Close, Eden It's an Endless World, Food Wars, Gantz, Gintama, Haaganai I Don't Have Many Friends, Hunter x Hunter, Itsuwaribito, JoJo's Bizarre Adventure (single volume ones vizmedia), Kagerou Daze (manga), Kagerou Daze (light novel), Knights of Sidonia, Livingstone, Monster Musume, My Love Story, Neon Genesis Evangelion (single volume ones), Nisekoi, No Longer Human (manga), Monthly Girl's Nozaki-Kun, One Punch Man, Sankarea, Slam Dunk, Sundome, The Flowers of Evil, The Testament of Sister New Devil, Triage X, Trinity Seven, Welcome To The NHK (manga) Welcome To The NHK (light novel), Yotsuba&!, Your Lie In April, & The Disappearance of Nagato Yuki-Chan.Now these I don't have on because they won't fit:Akira, Another (light novel), A Girl On The Shore, Ayako, Black Jack, Baccano, 20th Century Boys, Cross Game (omnibus), Dragon Ball (vizbig), Durarara! (light novel), Gangsta, Gunslinger Girl (omnibus), Goodnight Punpun (omnibus), GYO (hardcover), Inuyashiki, Jojo's Bizarre Adventure (hardcover), Kieli, Kizumonogatari, Monster (omnibus), Mysterious Girlfriend X (omnibus), Opus, One Peace (omnibus), Orange (omnibus), Planetes (omnibus), Pluto, Prison School (omnibus), Real, Rurouni Kenshi (vizbig), Saturn Apartments, Solanin, Strike The Blood (light novel), Sunny, Tokyo Ghoul, The Melancholy of Haruhi Suzumiya (light novel), Uzumaki (hardcover), Vagabond (vizbig), Vinland Saga (hardcover), What A Wonderful World, Yowamushi Pedal (omnibus), & The Kurosagi Corpse (omnibus).Also I have 2 Japanese manga series & they're Dead Dead Demons De Dedede Destruction & Shirokuma Cafe. These manga bags fit on Dead Dead Demons De Dedede Destruction but not Shirokuma Cafe.As you can see most of the ones they don't fit on are Hardcovers, Vizbig's, Vizsig's, Omnibus, & some Yenpress Light Novels.My reason for this list of manga/light novel is beacause you might have a manga that I listed on the fit size & it help you know that it will fit & you might have another manga that I don't have but that manga is the same size of the one you now know it'll fit. I hope this helps out a lot. This is my first long review, & I really do hope it helps. I'll attach some pictures of how they look on.Oh yeah. One day I had Berserk on my desk & spill my orange juice on accident & luckily Berserk was still on the manga bag so it didn't cause no damage. The juice just dripped off.
