These gun storage bags are the BEST! Well-made in the USA, will definitely keep all your firearms rust- and nick-free. The material is thickly padded with a rug-like fabric that has silicone in it to keep rust away. And since they are so well padded your guns will never get scratched or nicked when in storage. They come in a variety of different sizes. The flap closes with velcro. All my pistols are in these storage bags.

Protect you investment in a storage sock that absolutely won't promote rust and wards off dents, dings, & scratches. Obviously, I just purchased this one, but I've owned others for more than 30 years. These work. They're really cheap insurance for firearms.

VELCRO.
This p-3 size fits a full size 1911 with room to spare. Delivered quickly. Everything perfect. I thought I should say it has velcro closing flap which is nice but I didn't see it mentioned in the description. A nice feature that may go unnoticed until you have it in your hands.

Use these for everything, even airguns.
Been using them for years. Way better then gunsocks. These have some thickness giving them longer lifespan and actual protection. Still want to do thorough wipe down with everything you store or don't use regularly. Also wipe down your regular and favorites you use. It will not keep rust from forming or pitting etc. But it will make a big difference if you use them.
Keeps scratches and rust off even when storing in safes. Or putting in cases. Keeps oil off foam padding on hard cases, just good way to protect investments.
Most importantly they work and are worth the money. Face it we spend a lot for what goes in them. Best to protect them from humidity even if you use golden rod etc. to control humidity. If you live in low humidity its still worth using. They are cheap enough not too.
I've had them for years and every item I buy gets a new one.

I *really* like the Bore Stores cases. I've used the three primary sizes P-1, P-2, and P-3 and been very satisfied. They are well-designed and made of high quality materials and workmanship. They serve three main purposes for me... protect the guns from corrosion, protect the guns from striking other objects in the safe, and organizing my collection (the label tags).
