TACTICAL TIP: Against the jammed zippers

Who doesn't know this, finally it's here, the new backpack, but somehow the zipper doesn't run smoothly. Very annoying. A tried and true remedy is an old household remedy. Simply open the zipper completely and run the soap along all the teeth. Please do not use liquid soap, as you will not have success with that.

Once you have soaped both rows of teeth, simply slide the slider back and forth several times to ensure that everything is well "lubricated". Alternatively, candle wax can also be used. Good luck at unjamming your zippers.
