I received a CGC'd 9.0 Ultimate Daredevil & Elektra the other day off ebay, paid very little for it. However when I looked at it closely, there was what looked like cat hairs sticking out from under the sticker on the top of the slab. On the right of the slab, where the indent is, one side seems to be uneven. The comic itself has spine stress, a weared corner and the back cover has some serious stress. I thought that maybe the seller may have opened it and sealed it back but after asking about this on another forum, I was told to check the corner posts & that it would be hard to not notice if it was opened. The posts seem fine, inner well doesn't seem to have been tampered with but the top seal looks like it goes into where the CGC description label is.
It just seems sloppy in comparison to the other CGC's I have received, maybe this was a one off.
