An electronic pen has increased strength, especially a pen tip portion that is not bent or broken even if the electronic pen is slimmed down. A core unit includes a ferrite core on which a coil is wound and a core rod. The core rod is fixed from a first end of the ferrite core to a second end of the ferrite core at a position including a center axis of the ferrite core and projects at an end thereof from the first end of the ferrite core. The ferrite core includes a first coil non-winding portion on which the coil is not wound provided on the pen tip side of the ferrite core. In operation, the end of the core rod and part of the first coil non-winding portion of the ferrite core project from an opening of a housing of the electronic pen.

A highlighter with a see-through area comprising a housing having a hollow body and an opening, an ink reservoir disposed inside the housing for storing ink, a nib disposed at the opening and an ink feeder disposed inside the housing for transporting ink from the ink reservoir to the nib. The housing further comprises a cut-out section disposed behind the nib to provide the see-through area for a user. The see-through area allows the user to see a section of text before highlighting. Alternatively, a section of the housing behind the nib can be constructed using transparent material such as plastic to provide a see-through area for a user.

A multi-function pen and accessory devices and kits; specifically, writing instruments with a plurality of attachable and multi-functional personal care accessories and the like and kits. An accessory assembly may have a connector having a first connector end and a second connector end; a first accessory component configured to releasably mount to the first connector end; and a second accessory component configured to releasably mount to the second connector end.

An example combination tool for marking, measuring, and checking level includes a holder for a marking device (e.g., a soapstone). The holder has a body formed by a first side, a second side, a front side, a back side a top side, and a flat bottom side. A securement releasably secures the marking device at least partially within the body. Turning the securement in a first direction tightens the marking device within the body of the holder. Turning the securement in a second direction loosens the marking device in the body of the holder so that the marking device slides in and out through an opening formed in the front side of the body to adjust a position of the marking device for use in marking. The example combination tool may also include measuring markings, a level, a clip, and a grip.

A radio-opaque composition is formulated to enable a clinician to apply custom markings to a surface, such as a patient's skin or a surgical drape on the patient. More specifically, the radio-opaque composition may be used to write on the surface. The markings may be well-defined and contrast with the surface to which they are applied. Such a composition may include a liquid radio-opaque component that includes one or more radio-opaque materials that have been dissolved in a solvent, as well as a solid radio-opaque component with particles of one or more radio-opaque materials dispersed throughout a carrier, such as the solvent of the liquid radio-opaque component. Marking apparatuses that may be used to write with the radio-opaque composition are also disclosed, as are methods for using the radio-opaque composition.

Styli for generating alert notifications to prevent unintentional marking of interactive devices are disclosed. A disclosed stylus includes a housing and a processor. The housing is to interchangeably receive a physically marking nib and an electronic marking nib. The processor is carried by the housing. The processor is to determine a received nib is the physically marking nib. The processor is further to determine a distance between the stylus and an interactive device satisfies a threshold. The processor is further to generate an alert notification based on the received nib being the physically marking nib and the distance between the stylus and the interactive device satisfying the threshold.

A multifunctional writing device comprising a hollow body, wherein the hollow body comprises one or more cavities configured to store a protractor, a ruler, a set square thirty/sixty-degree (30/60) triangle, a set square forty-five-degree (45) triangle, a compass needle, a USB flash drive, a stylus, and an eraser. A first writing member comprises lead and a mechanical pencil system being provided in a first portion of the hollow body. A second writing member comprising a pen system being provided in a second portion of the hollow body. A magnetic lock attaches and stores a protractor, a ruler, a set square thirty/sixty-degree (30/60) triangle, a set square forty-five-degree (45) triangle, and a compass needle inside a cavity. A protractor, a ruler, a set square thirty/sixty-degree (30/60) triangle, and a set square forty-five-degree (45) triangle are removed from a cavity by pulling rectangular strip top portion.

A writing instrument for alternating between a active stylus tip and an ink pen tip which is retractable from and displaceable through an annular opening at one end of the writing instrument is disclosed.
