Good lord Larry! Mine started to look like this a while back. I opted to get several large spyderpac, fill them, and store them in the safe instead. They take up a ton less space and protect the knives (easier access to your AR15 as well), and store the boxes in my garage in a tote. It's soon much easier to fondle and it takes up soo much less space. You will thank me later if you do this lol.
P.s. I also did this with my GEC as well and just bought little silica gel packs from Amazon. I just tucked one in each pocket. Never had any spotting and kept my wax paper and tubes prestine! (Stored the in my "knife box" tote as well.
