Say hello to this simple way to send notes to students! A must-have for classroom supplies and stationery, these postcards feature a colorful watercolor design of stripes in rainbow hues. Students can use these to send a message home to their parents, or teachers can write a welcoming note on each one then leave them on desks for the first day of school. Paper.
