Dress your lunchbox up for seasons, favorite colours, pets and more. Can't decide on just one? Purchase several and mix it up different days of the week.
Dry your box thoroughly after washing and before re-attaching the magnets. If the magnets get wet it can cause the magnetic material to degrade and attach itself to the top of the lunchbox (which is magnetic). This can cause rusting. Making a thick paste of vinegar and baking soda, leaving it on the marks for at least an hour and then scrubbing it off and rinsing will clean the spots.
