Traveler's Factory Leather Coaster Circle CamelTRAVELER'S FACTORY original coaster featured here in Camel, is made of the same leather as the TRAVELER'S notebook. The leather is cut into a round shape, then our TRAVELER'S notebook logo is engraved on it. It is a perfect size for a mug and would make a great addition to your daily coffee ritual. Just like TRAVELER'S notebook, the more you use it, the more it will age and enhance the taste of the leather.
