Most covers consist of a clip, a flap, a cover band and an inner cover. The clip allows you to attach the pen to a pocket, cover or item of clothing. However, some caps don't come with a clip and are usually advertised as “no clip”. The finish comes on top of the cap and helps keep the clip in place.
The cover band helps keep the inner cover in place. The inner lid remains inside the lid and allows the ever-popular “pressure cap” to be placed. In addition, the inner caps help keep the ink fresh and ready to use. The pen also has a good balance and writing with the pen in the long term won't cause any fatigue.
