Comic book sleeves If you are going to buy and sell comics then you need to protect your comic collection.
Comics will become damaged and lose value if you do not put them in a comic book sleeve.
Simply putting them in an old shoe box is not enough.
Comic book sleeves are plastic transparent covers that allow you to safely handle and admire your comics.
The sweat in your hands is acidic. This acid will damage the pages and the cover art of your comic bok. This reduces the grade of your comic and the value of your comic as well.
If you know that you have a valuable comic in your collection, or if you suspect that one of your comics may be worth some money. Then please put it in a sleeve. If you have a very large collection of comic books, you don't have to put all your comics in sleeves.
Simply have your comic collection appraised and put the most valuable ones in comic book sleeves.
