Magnetic One Month Calendar 4' x 6'

Extra-large, 4' Tall x 6' Wide, American made one-month magnetic dry erase calendars. We use a process that we call OptiPrint® to create these permanently imprinted, magnetic receptive 30-day calendars with our exclusive OptiMA dry erase writing surface.

Super large day blocks give you plenty of room for the day's task no matter which size calendar you select. There is also plenty of room for notes, etc. on each unit. You have four different size options to select from but customization is always available since we make every unit right here in our own factory. Contact us for details.

Our magnetic dry erase boards have an exceptional dry erase writing surface. Each of these boards is made and printed in the U.S.A.

Tip: It is not recommended to clean these boards with anything containing ammonia which is found in most glass cleaners.
