This is for making impressions on sealing wax in the form of the Chalice, a symbol of faith for Unitarian Universalists. This particular Chalice is the one adopted by the Unitarian Universalist Fellowship of Huntington (UUFH). UU a very open and accepting faith, encouraging each person to find their own spiritual path. There is no dogma - atheists and humanists sit side by side with monotheists and polytheists.
The top of the handle is marked to make it much easier to align the impression and avoid setting it upside down or crooked.
