I have bought it numerous times from S&W, since I wrap all guns I ship in it.
As advised, simply call customer service. They'll sell you all you want. My last order was 400 sheets.
Hey GSXUNV04...the purpose of the paper is to prevent rust...it is a treated paper (VCI chemical I believe) that inhibits rust. S&W ships their guns in it (or they used to anyway). I wrap ALL my guns in this paper, even long guns if they are going to be stored for a long time...hope this helps...
I bought a roll 36" wide, long enough to wrap a semi trailer for about $60 from Amazon. Just cut off what you need and keep rest enclosed in plastic bag (provided) until ready for use. You can also buy a "mega case" of 9x9 sheets for about $40. Just search "VCI paper" on Amazon or Google it. Can also use it in your ammo storage. S#*T you could also wrap your ole "65" Mustang in it. Caution, unless she's a robot, wrapping your ole lady in it will not stop the aging.
