13" open-end zipper. Molded plastic teeth. Very dark navy blue. The pictures are in bright light. They look black in medium and low light. 

I get 5mm when I measure zipper width. Nothing is stamped on the back. 

All but one of the zippers have rectangular pulls. Let me know if you'd like the one with the rounded pull.  

This listing is for ONE zipper. 

See other listings for different lengths.  

These zippers were acquired from a clothing company that went out of business. 

Contact me for discounts on larger orders (of other zippers), we'll figure out a total price, and I'll make you your own listing.

See my store, Brown Table Deals, for more zippers and other items.
