With gaming comes drinks, with drinks come a ruined gaming table. So, we made this answer with a quality DND themed coaster for gaming! 

These coasters are made out of thick hardboard with a very nice texture to them.  They are also hand pressed in a town in Minnesota that's so small one would expect there to be more issues with Orc raiders.  Because of the hand made nature of these items there may be slight variations between each coater.
