Perpetual wooden calendar blocks are the perfect gift for Breast Cancer Awareness, teacher, sorority, admin assist, boss & secretary. Also use in classroom, dorm, Greek Life, office, desk and kitchen windows! Great photo props for save the date, too! The blocks are hand cut from poplar wood, hand sanded & painted. Top quality acrylic non-toxic paint that will stay bright and vibrant is applied. I use professional high performance grade vinyl for the letters and numbers. Blocks measure 3" x 1 1/2" and 1 1/2"
