On our stock bags the zippers are brass.  We have in stock many other types of zippers such as nickel, nylon and various sliders ( part that slides/open/closes zipper chain).  If we do not have a particular zipper and/or slider combination, we have hundreds of vendors we our already established with and can acquire custom components in a few hours or days in almost all cases.

Of course we can incorporate any type of closing system that may be needed for a bag or pouch.  This may be snaps, velcro, ties, grommets etc.  As always please contact us with any custom or out of the ordinary request.
