A user-replaceable e-liquid reservoir for dispensing e-liquid, the reservoir being inserted into, or otherwise attached to, a portable, personal e-cigarette device and engaging with an electrical or electronic pump fluid transfer system in the device, the device including: an electrical or electronic pump, being configured to transfer e-liquid from the e-liquid reservoir to an atomizing unit in the device, the pump delivering a pre-defined or variable quantity of e-liquid from the reservoir; and in which the reservoir is not user-refillable.

A promotional item comprises a writing instrument having a substantially flat surface and a box carrying the writing instrument and having a top with a flat surface. A matching recess in the box has an opening in the flat surface matching a profile of the writing instrument. The flat surface of the writing instrument is flush with the flat surface of the box when the writing instrument is carried by the box and positioned in the recess. Promotional indicia is disposed on the flat surface of the box and the flat surface of the writing instrument.

A user-replaceable e-liquid reservoir for dispensing e-liquid, the reservoir being inserted into, or otherwise attached to, a portable, personal e-cigarette device and engaging with an electrical or electronic pump fluid transfer system in the device, the device including: an electrical or electronic pump, being configured to transfer e-liquid from the e-liquid reservoir to an atomizing unit in the device, the pump delivering a pre-defined or variable quantity of e-liquid from the reservoir; and in which the reservoir is not user-refillable.

A method of converting a static display to a dynamic display includes providing a static display and removing a portion of the display to form a cutout area. A dynamic display sheet is positioned at the cutout area. The dynamic display sheet includes a first layer comprising a plurality of three-dimensional static programmable electrochromic (SPEC) particles; a second layer comprising a positively charged conductive sheet; a third layer comprising a negatively charged conductive sheet; a laminate layer; and a control element comprising a processor for activating the SPEC particles to switch from a first to a second colored state; wherein the second and third layers are respectively positioned on either side of the first layer, and the laminate layer encompasses the first, the second, and the third layers. The dynamic display sheet is activated to cause the SPEC particles to selectively flash between the first and second colored states.
