These 7/8-inch round green buttons add beauty and style to any garnment with their subtle yet fascinating pattern. Purchase these buttons secure in the knowledge that yet again your choices are making a difference; to quote the supplier: "These international buttons are made from the South American tagua nut. The tagua nut has been the focus of ecology initiatives worldwide. The use of the nut provides a revenue source and reason not to harvest South American rain forest and deplete the ozone layer."
