I ordered these to wear in honor of my sister who is a breast cancer survivor. This set of 15 metal pins are enough for us to pass our to our family members to wear. They are about 1 1/2" high and with bright pink enamel. They are metal alloy and are high quality. Made to not rust or damage your clothing. The back has an easy to remove clasp so just slide through your shirt and fasten the back. Looks good on any outfit and shows your support for breast cancer patients, family and survivors. Definitely recommend. #rankboosterreviews #BigOtters #sponsored https://www.amazon.com/dp/B086X6V3TJ
