Embodiments of the invention are directed to a roller ball marking instrument for use with paint, a method for assembling the roller ball marking instrument, and a system for delivering paint. The body of the marking instrument includes a reservoir for storing paint. The body is coupled to a fibrous roller ball via a retaining ring. The roller balls sits within a partially-enclosed cavity in the center of the retaining ring. A least part of the roller ball protrudes through an opening in the retaining ring. Paint in the reservoir moves first through an opening at one end of the body and then through an open center of the retaining ring. The paint is transferred to the roller ball. The roller ball rotates freely within the cavity of the retaining ring and transfers the paint to a writing surface.

The present disclosure provides instruments, kits and methods for growing a plant. In some embodiments, a plant producing writing instrument is provided. Such writing instrument may include a housing having a writing end and an opposing non-writing end. In addition, a capsule with one or more seeds may be disposed at the non-writing end of the housing. The capsule may be degradable after placement in a moist soil to release the one or more seeds.

A protective element for a writing tip of a writing instrument including a cap extending longitudinally along a central axis and configured to be fitted onto a body of the instrument, and a clip extending substantially parallel to the central axis from a first end fixed to the cap to a free end. The clip and the cap are in one piece.

The present disclosure features tube insertion devices that are configured to allow a user to manually insert a hollow tube into a receiving bore, e.g., a pen tube into the bore of a blank. The disclosure also features methods of using such devices. In some implementations, the devices comprise (a) a pair of elongated arms, each arm comprising a gripping portion and an insertion portions, each of the insertion portions terminating in a distal tip, and (b) a connecting portion joining the arms such that the arms pivot about the connecting portion in a plane defined by the arms when the gripping portions are pressed together by a user. Each of the insertion portions preferably includes a relatively wider proximal portion and a relatively narrower distal tube-carrying portion, the change in width between the proximal portion and the distal portion defining a stop surface.

A marker and nib assembly that allows for multiple uses before needing to replace the nib. The present invention comprises a nib, a marker body, a marker neck, and a pin. The nib further comprises a plurality of holes allowing the nib to be adjusted and reused multiple times. When the nib is worn out, it can be raised to align with the next hole, and the excess material can be cut off.
