WANDRD Worryless™ Locking Zipper Pullers - Secure Your Travel Essentials - Zipper Locks for Travel Gear (Arches Red)

Love these zipper pulls with locks, they match so many shades and fit any zippers, and take up no extra space while looking good, which is everything you want when dealing with backpacks. Worth the premium price. Using them on my two Tobiq packs which have numerous double zips with nary a lock option. Note in the photo it shows I can even lock the single zip on the side laptop pocket to the far side zipper on the front double zip and it will secure both the front pocket from opening and the laptop pocket. And color code the zips so I can quickly find my gear in the monochromatic bag. Only thing missing is a glow in the dark option.

I had to get the hang of using them. It willSlow down and help discourage a thief to try to unzip your bag. It also makes it easier to unzip and zip with the zipper when you unlock. I would buy again!
