This beautiful pin is a great memento from your Walk experience, or a great way to thank your donors! Material: Imitation hard enamel with military (butterfly) clutch backing. Size: 1-1/4”. Best of all, for every Avon Walk item purchased at the Avon Walk Store online, 100% of the net proceeds are donated directly to Avon Breast Cancer Crusade (this ranges from approximately 50% to 75% of purchase price, depending upon the item) to support programs that help people get the breast cancer care they need and to support life saving research.
