This is an Black Acacia twist ballpoint slimline pen and matching mechanical pencil set. Both are made with 24K gold plated accents and a black stripe clip. The pen uses a Cross® style refill and is made with a durable twist mechanism which will hold up for years. To replace the refill, pull off top of pen above the center band and twist out the refill. The pencil is specially designed to feed the correct amount of 0.5mm lead with each click of the plunger top. The eraser is under the plunger cap and the eraser is pulled out to refill the pencil with 0.5mm leads. A highly polished lacquer finish was used to protect the wood. These hand made pens and pencils make wonderful gifts and are absolute treasures to own!
