Parallelogram season... Magnet.
$4.50

I'm so glad I learned all about parallelograms in high school math instead of how to do my taxes. It comes in so handy during parallelogram season. 

Meriwether custom designed refrigerator magnets are super strong. They look great, will make you giggle and will easily hold whatever papers you'd like to slide under them.

Magnet Dimensions: 3" x 2"
