A multi-purpose combination writing instrument comprising: at least three individual writing instruments, each individual writing instrument comprising a barrel having a proximal end and a distal end; a base having opposing first and second ends, the first end of the base comprising at least three receivers, wherein each receiver is adapted to receive the proximal end of the barrel of a corresponding individual writing instrument, and the second end of the base having at least three tape flag platforms disposed therein; and a cap rotatably mounted on the second end of the base over the at least three tape flag platforms, wherein an opening in the cap provides access to one tape flag platform at a time as it rotates around the second end of the base.

A compact writing instrument includes a barrel and a cap. A majority of a length of the barrel and a writing element carried thereby may be received by the cap when the barrel and the cap are placed in a stored position, providing a compact stored arrangement. The cap may be secured to the barrel in a writing arrangement that extends a length of the writing instrument significantly; for example, to a conventional writing instrument length. Engagement features of the cap and barrel may include steep threads that enable the cap to be assembled with and disassembled from the barrel with one rotation (360°) or less. A clip on the cap may include a closed end that defines a receptacle, with the closed end and receptacle extending beyond a corresponding end of the cap. In addition, the closed end and receptacle may extend partially over the corresponding end of the cap.

A thermochromic writing instrument including a writing body, storing a thermochromic ink therein, stored in a barrel; an operation body provided in the barrel to be operated to longitudinally move the writing body; a nib of the writing body configured to be capable of appearing from a front end of the writing instrument, wherein the writing instrument 1 further includes a friction unit, for rubbing handwriting in the thermochromic ink and capable of thermally changing the color of the handwriting by frictional heat generated at that time, and at least one clip body as the operation body, the friction unit 10 is provided at a rear end of the barrel, and the clip body is provided in an area other than the rear end of the barrel.

A writing instrument includes a barrel and a cap capable of being assembled with and secured to the barrel. The barrel carries a writing instrument. The cap carries a clip. A free end of the clip includes a detent that can be received by a corresponding indentation of an exterior surface of an external portion of the barrel when the cap is assembled with the barrel. The detent of the clip and the indentation of the barrel are capable of securing the cap and the barrel in their assembled relationship. The writing instrument may be compact. Methods of using a writing instrument include securing a cap of the writing instrument to a barrel of the writing instrument by causing a detent of a free end of a clip of the cap to engage a corresponding indentation of an exterior portion of the barrel.
