Wood is a very durable natural material but it can be damaged by a number of factors. Avoid storing your wooden pen in direct sunlight as it may cause premature aging and fading of the wood. Exposure to extremes of heat or cold – say storage in a car – may dry out the wood and cause cracking. Keeping your wooden pen in a pocket or purse without a protective sleeve may result in scratches from exposure to keys, coins or other harsh objects. Dropping your wooden pen onto a hard surface may result in damage. Use a soft cloth to buff the pen as needed but don’t use any cleaning agents. Furniture care products or paste waxes are easy to apply and will buff to a high sheen.
