【New, Unopened】 Hobonichi Whiteboard Calendar 2026 MOTHER2 DESK TOP Desk Size Includes Whiteboard Marker The Hobonichi whiteboard calendar, a popular staple since 2006, is a full-surface whiteboard calendar that allows you to write a lot and erase easily. Whether it's a change in plans, tentative appointments, quick notes, or messages for the family, you can write them with the included whiteboard pen, erase them with a swipe, and rewrite them. I have many calendars, so I'm putting this one up for sale. Anyone interested?
