These Coasters are in support of those battling cancer. We have tried to find the ribbon colors for all cancer types and incorporated that into these coasters. Each coaster is made of hardboard with a cork backing. The face of each coaster will have a cancer heart printed on it. Each heart will be the ribbon color (if the ribbon has more than one color it will be one of them.) The cancer name will also be in the ribbon color (if more than on color then all colors will be in the name.) We also have a Caregivers and generic option. We are allowing up to 4 different cancer types to be ordered on one (1) order. If you choose more than one (1) cancer type please put qty of coasters behind cancer name (See short description for example) 10% of the proceeds from the sale of these items will be split between the two cancer centers we dealt with Coasters will go to Cancer Treatment Centers. Please type cancer type(s) into special instructions so we can customize the coasters with, to help others battle this terrible disease.
