I pulled a box of family photos out of the attic and half of them had fused together from the heat. These containers actually seal out moisture and temperature swings so that never happens again.



















Sealed containers help, but moisture still sneaks in when you open and close them. These packs keep humidity from slowly destroying everything inside.



















Throwing loose photos into a plastic bin is how they scratch, stick, and curl. Individual sleeves were the difference between my photos surviving and my mom's getting destroyed.















I had no idea my attic was hitting 140 degrees until I stuck a thermometer up there. Knowing the actual conditions changed everything about where and how I store things.



















Regular cardboard breaks down and releases acids that eat into paper and photos over decades. Found that out when I opened a box of my grandparents' letters and they were turning brown at the edges.
