Short (5/8") pull on an auto-lock body.
This is one size of zipper that most stores don't carry. It is quickly becoming a favorite size for packs. It is big enough to be very strong but supple enough to bend around the pack.
I started carrying this size for a woman that makes cases for musical instruments and now use it for many applications.
It is 9mm across the coil.
I have just received WHITE. So now have white & black in this size.
Coil is nylon. Polyester tape.
