Hi, I picked up this copy of FFIII a few years ago and I put it almost right away in a protector box. I noticed these little bumps oe bubbles on one side of the box. They're not too "high", the cardboard underneath doesn't seem damaged and while I did remove a sticker with just a little bit of lighter fluid back then, the part where the sticker was is on the opposite side, with no bumps/bubbles where the sticker or the lighter fluid was, so while I'm not sure, I don't think it's that.
They're not exactly too visible either, you can only see them in certain lightings (hence the poor quality pictures, I couldn't pick up the bumps/bubbles with my phone camera's flash), but still, I'm genuinely curious and a bit concerned on what they could be, as I wasn't able to find anything online resembling that.
