The Pull Du Jour (PDJ) is a fully integrated loop and pull. No more assembly required, just loop it through the top and bottom holes of the metal or plastic zipper pull and it's good to go. 3 1/16 iches / 80 mm from tip to tip, the loop itself is 2 15/16 inches / 62.5 mm. They come in packs of 4, either 4 black, 4 orange, or 2 black and 2 orange, and they have a TB on the pull. They're chunky enough to feel good in your hand and light enough that they won't make any noise while you walk. Not much more to say about 'em.
