These Mylar bags are crystal clear and allow for maximum visibility for comics. They never wrinkle with age and you can see the book along with any and all imperfections on the book itself. Once you go Mylar, you will net want to use regular bags and boards again. They are twice as expensive as regular bags and boards but well worth it. Comics really stand out in these bags.
Good price for acid free backer boards. The boards are well made and fit very well in the size comic bags the boards are made for. Gerber is the go to company for me when it comes to comic book protection.
These comic boards are excellent quality. They're strong, while also being flexible. I would buy them again and recommend them to others looking for comic boards.
