Pink Ribbon Sheet Protectors feature a pink reinforcement strip to promote Breast Cancer Awareness. Support the search for a cure with these sheet protectors that store and protect documents and reference materials. Proceeds from the sale of each box will be donated to the National Breast Cancer Foundation (NBCF) to promote breast cancer awareness and fund mammograms for those in need. Top-loading design eliminates the need for hole punching. Archival-quality polypropylene means print won't stick to sheet protectors. Strong, pink, reinforced binding edge prevents tears, even with heavy use. Standard-weight sheet protectors are designed for use with letter-size document storage in standard three-ring binders.
