I didn’t buy these for comic books, but to wrap fabric around. They work very well for this purpose.I use them for protecting my valuable comics AND believe it or not for writing notes to myself for ideas I get in the middle of the night.Because of the archival quality of these boards , I bought them for my fabric storage . I’m a self confessed fabric hoarder and I needed to find a way to store my fabric in visually pleasing and convenient stacks . These boards are perfect and hold up to 5 yards!the corners had minor damage but it was exceptable.As a product I liked it but I ordered 200 and only got 100. Disappointed.I use these to put fabric on for quilting. They are great.The boards arrived quickly and are perfect. Thanks so much!Seriously annoyed that bags are Silver-Age, but boards are Modern/ Current. May seem trivial, but comics sliding can bend spine!Also quality of bag is not that good - will require re-bagging much sooner than normal.
