All my pens need little maintenance as I have sealed the wood with a hard and durable finish to protect it. An occasional wipe over with a soft cloth to remove fingerprints if you wish. More care and thought should be given to where you leave it. Although tough and durable for everyday use, please do not leave it near radiators, on car dashboards or near direct heat sources. The wood is dry, but different woods expand and contract. Leaving any wood in direct sunlight will fade darker woods, and lighter woods will darken.
