So you collect.
Maybe it started with one issue. Maybe you inherited your uncle’s long boxes from the 70s. Maybe you just really like having stuff on your shelves that makes you happy when you look at it.
Whatever it is, you’ve got more of it than your house can handle now. I’ve been there. My dining room table was covered in slabs for three months before I finally admitted I had a problem.
Here’s the thing nobody tells you when you start collecting. The stuff wants to take over. It multiplies when you’re not looking. One minute you’ve got a tidy short box under your bed, next minute you’re tripping over long boxes every time you go to the bathroom.
So yeah, storage makes sense.
But you gotta be careful. Because I’ve seen too many people wreck their collections by shoving them in the wrong place and forgetting about them.
Why Humidity Is Your Collection’s Worst Enemy
I know you’ve heard this before but listen. Paper is like a sponge. It just is. You put paper somewhere damp, it soaks up that moisture. Then it gets wavy. Then it gets those little brown spots. Then it gets mold.
Mold is the end. Once it shows up, you can’t really fix it. You can try, but that book is never the same. And it spreads. Open one moldy box and all the boxes around it are in danger.
So when you’re looking at storage units, you want climate control. Not the cheap outdoor unit with the metal door that gets roasting hot in summer. You want the kind that stays the same temperature year round.
We set up our climate control specifically for people storing things like this. Because we know what happens when you don’t.
Don’t Skimp on Your Boxes
Most people grab whatever cardboard they can find. I get it. Boxes are expensive and you just spent all your money on a silver age key.
But those grocery store boxes are a problem. They’re usually acidic. They attract silverfish. They’re not designed to stack. I had a guy tell me once he lost a whole box because the bottom gave out and everything fell on concrete. Books got dented corners. He was not happy.
Get proper comic boxes. Short boxes are easier to carry and stack better. Long boxes hold more but they get heavy fast. And don’t stack more than three high. The boxes on the bottom will start to crush and that pressure transfers to your books.
Graded Books (Slabs) Need Special Attention
If you collect slabs, you already know they’re a pain to store. They don’t fit in normal boxes. They’re heavy. They’re bulky.
And whatever you do, do not stack them flat.
I see people do this all the time and I want to scream. Those slabs are heavy. Stack five of them on top of each other and the one on the bottom is under serious weight. The case can crack. The inner well can crack. I’ve seen a CGC 9.2 get ruined because someone stacked ten slabs on top of it for a year.
Store them upright like books. Or get slab boxes designed specifically for them. They cost a few bucks but it’s cheaper than replacing a high grade book.
Your Bags and Boards Are Probably Degrading
You know those comics you bagged and boarded ten years ago? Those bags are breaking down right now.
The cheap poly bags turn yellow. They get brittle. Sometimes they start sticking to the cover. I’ve had to peel old bags off books before and it’s terrifying. You don’t know if the ink is gonna come with it.
Mylar is the answer. It costs more upfront but it lasts decades. It stays clear. It doesn’t react with the paper.
Same deal with boards. Regular boards aren’t acid free. Over time they leach acid into your comic and the pages turn brown along the edges. You won’t notice for years but eventually you’ll pull a book out and wonder why it looks so old.
Prep Your Books Before Moving Day
Don’t do all your organizing the night before you move.
I made this mistake once. I was up until 3am re-bagging books, rushing through it, not paying attention. I handled everything with sweaty hands because I was stressed. My fingers left marks on a couple covers. Nothing major but still. It bothered me.
Take your time. Spread out on a table. Wash your hands first. If you’re dealing with high value stuff, wear gloves. Cotton gloves are cheap.
And for the love of God, label your boxes.
I know you think you’ll remember. You won’t. I have a box in my unit right now that just says “stuff” and I have no idea what’s in it. It’s been there for two years. I’m scared to open it.
Memorabilia Is a Whole Different Beast
If you’re storing action figures still in the package, bubble wrap is not your friend long term.
The plastic bubbles on action figures and the bubble wrap can react with each other. I’ve seen sealed figures come out of storage with this weird cloudy residue on the packaging. It doesn’t come off.
Use acid free tissue paper. Or unbleached cotton fabric. Something that breathes and won’t chemically interact.
And heavy stuff goes on the bottom. If you’re storing statues or omnibuses or anything heavy, put them on the floor of the unit, not on top of your comic boxes. I had a guy tell me his Bowen statue tipped over and crushed a short box full of Fantastic Four books. Just think about that.
How to Actually Set Up Your Storage Unit
Don’t put boxes directly on the concrete.
Concrete sweats. Even in a climate controlled unit. Moisture comes up through the floor. Put pallets down or get wire shelving. You want air moving under your stuff.
Leave yourself room to walk. I know the storage unit sales guy told you to pack it tight but you need to be able to reach your stuff. If you have to move fifteen boxes to get to the one in the back, you’re never going in there. And that defeats the whole point.
Keep what you use most near the front. Your reading stack, your trade pile, whatever you’re actively working on. Everything else goes in the back.
Don’t Ignore Security
Your collection has value. Maybe not to everyone, but to you. And if you’ve been at this a while, you’ve probably got more money tied up in those boxes than you want to admit.
Good lighting matters. Solid locks matter. A facility where people actually pay attention to who’s coming and going matters.
We keep our place well lit and we don’t mess around with security. Because I know what it’s like to worry about your stuff.
Bottom Line
Storage isn’t dumping your collection somewhere and forgetting it exists. It’s giving your stuff room to breathe until you’re ready to pull it out and enjoy it again.
Spend the money on good supplies. Get climate control. Don’t cut corners. Your collection worked hard to get here. It deserves to be treated right.
If you want to come see our units, swing by. We’ve got climate controlled spaces and we know how to treat collectors. We’re collectors too. We get it.
