Leather products will darken over time, particualrly if left in direct sunlight. Some amount of warping may occur over time as well. To correct warping issues, don't be afraid to bend the coaster to straighten it out. The leather can take a beating and you won't damage any of the writing on the surface by bending it! The wood coaster is treated with a polyurethane coating and should not require maintenance.
