Fix the Latch, Toss the Zipper

If the latch on your lunch box is broken, you can almost always fix it for a few dollars. A broken zipper is usually not worth the fight.

Latches on hard-sided lunch boxes and coolers are held on by a couple of screws. Find the model number, search for a replacement latch, or grab a generic one from a hardware store. Ten minutes with a screwdriver and you’re done. Even a nice latch costs less than a new lunch box.

Zippers are a different story. On a soft-sided lunch bag, the zipper is sewn into the fabric. Replacing it means seam-ripping, re-sewing, and getting the length right—that’s more work than a $15 bag is worth. The one exception: if the teeth are fine but the slider is slipping or busted, you can often pry the old slider off and snap on a new one with a zipper repair kit. That fix works maybe half the time and costs five bucks.

If the teeth are missing or the track is split, just replace the whole lunch box. The repair won’t hold, and a bag with a failing zipper is usually on its last legs anyway.

Spend your Sunday somewhere better than fighting a lunch bag zipper.
