## Abstract

A pen or pencil comprising a casing, the outside contour of which forms two or more gripping surfaces (12, 14, 16). There is at least one intermediate region (18, 20, 22) which is between two adjacent gripping surfaces in the peripheral direction and in which the outside contour of the casing is radially within a notional intersection line (24) of the two adjacent gripping surfaces.

## Claims

### Claim 1

A pen or pencil comprising a casing extending from a rear end of said pen or pencil to an area adjacent to a writing tip of said pen or pencil having an outside contour, the outside contour is provided with two or more arcuate gripping surfaces, at least one indented intermediate region located between two adjacent gripping surfaces in a peripheral direction, and the outside contour of the casing is radially within a notional intersection line of the two adjacent gripping surfaces, wherein the intermediate region extends in the peripheral direction over an angular region (β) which is between 30% and 70% of that angular region (α) over which one of the adjacent gripping surfaces extends.

### Claim 2 (depends on 1)

A pen or pencil according to claim 1, wherein an internal space of the casing is at least portion-wise circular-cylindrical.

### Claim 3 (depends on 1)

A pen or pencil according to claim 1, wherein the outside contour of the intermediate region has concave and/or flat portions.

### Claim 4 (depends on 1)

A pen or pencil according to claim 1, wherein the outside contour of the intermediate region is at least portion-wise U-shaped or V-shaped in cross-section.

### Claim 5 (depends on 1)

A pen or pencil according to claim 1, wherein the intermediate region extends in the peripheral direction over an angular region (β) which is between 40% and 60% of that angular region (α) over which one of the adjacent gripping surfaces extends.

### Claim 6 (depends on 1)

A pen or pencil according to claim 1, wherein the intermediate region extends in the peripheral direction over an angular region (β) which is between 45% and 55% of that angular region (α) over which one of the adjacent gripping surfaces extends.

### Claim 7 (depends on 1)

A pen or pencil according to claim 1, further including a colour marking in a boundary region between the intermediate region and an adjacent gripping surface.

### Claim 8 (depends on 1)

A pen or pencil according to claim 1, wherein at least one gripping surface is flat.

### Claim 9 (depends on 1)

A pen or pencil according to claim 1, wherein at least one gripping surface is of an arcuate configuration in cross-section.

### Claim 10 (depends on 1)

A pen or pencil according to claim 1, wherein at least one gripping surface is of a circular arcuate configuration in cross-section.
