Love these only they are a little flimsy - MTM Ammo Can Organizer Insert

I love how organized these help make all your ammo but the sides are a little flimsy though. I noticed they were nice and straight when I got them but just leaving them sit in my living room for a week or two before we turned on the central air it got to around 80° and I noticed the sides of these started kinda warping a little bit. The sides were no longer nice and straight with them still bundled together like they were when I first got them. They still work fine but they aren't exactly straight anymore. Also a buddy of mine has these and he found if you don't want a mess of bullets mixing together in the top tray especially he had to glue two pieces of cardboard together then cut it to fit inside the ammo can then he just punched a couple holes through the middle and tied some Paracord through them to make a handle. That keeps everything pretty snug and he doesn't have ammo mixing nearly as bad if it gets tipped anymore. I still have to do this with mine yet.
