To fix a broken or stuck zipper in no time you just need to use this very quick trick: it solves the situation immediately

If the blockage persists, apply a little more graphite and try again.

In some cases you may need to insist for a few minutes.

💡 Emergency alternatives (if you don’t have a pencil)

Lip balm or lipstick (applied sparingly)

Dry soap (rubbed lightly on the zipper)

Candle wax

🚫 What NOT to do

Don’t force the zipper too hard: you could break the slider or the teeth.

Do not use oily liquids (such as cooking oil): you risk staining the fabric.
