Game Of Thrones Slate Coasters: Game of Stone
Each coaster is laser engraved with a different house symbol and you get four designs (Lannister, Stark, Tyrell and Targaryen). Laser engraving is pretty impressive considering they didn’t have lasers in Westeros. Besides, you wouldn’t want them sword engraved because you would be left with a bunch of rubble. The men of Westeros don’t really know how to engrave without hacking and slashing things to bits.
