YKK | オープンエンドファスナー | 成形プラスチック | ブラック | #5

The molded plastic teeth slide smoothly and the open-end design makes it perfect for a duffel bag that needs to fully open flat. Used it for a quick repair and it’s held up through a few heavy loads without any snagging.

Replaced the broken #5 zipper on my go-to duffel and it slides way smoother than the original did. The molded plastic teeth feel sturdy and the open-end pull apart works exactly like it should. Took me about twenty minutes to sew in and now the bag's back in rotation.

Used it to replace the zipper on my favorite backpack when the old one gave out, and the #5 molded plastic teeth glide much smoother than I expected. The separating design made installation straightforward, and the black color blends in perfectly. Really happy with how solid it feels.
