The grey seal (Halichoerus grypus, meaning “hooked-nosed sea pig”) is found on both shores of the North Atlantic Ocean. It is a large seal of the family Phocidae or “true seals”. It is the only species classified in the genus Halichoerus. Its name is spelled gray seal in the US; it is also known as Atlantic seal[2] and the horsehead seal.[2][3] https://en.wikipedia.org/wiki/Grey_seal
Sealing wax is a wax material of a seal which, after melting, hardens quickly (to paper, parchment, ribbons and wire, and other material) forming a bond that is difficult to separate without noticeable tampering. Wax is used to verify something such as a document is unopened, to verify the sender’s identity, for example with a signet ring, and as decoration. Sealing wax can be used to take impressions of other seals. Wax was used to seal letters close and later, from about the 16th century, envelopes. Before sealing wax, the Romans used bitumen for this purpose. https://en.wikipedia.org/wiki/Sealing_wax
