We are proud to support Breast Cancer Awareness and Research. Show your organization's support and affiliation for this worthy cause. The 12" desk ruler gives people a chance to show support everyday. We will donate 10% of the 1st column price to Breast Cancer Research. So even if you buy in large volumes to take advantage of the quantity discount, 10% will still be donated off of the highest price listed. Working together we can help put an end to breast cancer.
