This appears to be from around the 1970s. It's a large TALON ZIP zipper, 1980mm long. It's deadstock. It's in good condition with no damage like wrinkles. The slider is on both sides, allowing it to be opened and closed from either side. It was likely used on the opening of something like a US military tent. I am selling two other identical items, for a total of three. I think this is a very rare item. How about it? Thank you. *Please note that shipping will not be available on October 23rd and 24th. Thank you for your understanding. 【Size Details】 * Zipper Length: 1980mm * Total Length: 2080mm * Zipper Width: 9mm * Total Width: 57mm
