The invention relates to a device that can be used to try electronic cigarette liquids, intended for the retail sale of electronic cigarettes, providing a system that allows the end client to try different electronic cigarettes without having to put together a complete assembly for each type of liquid, said device taking the form of a block provided internally with a set of clearomizers and vacuum pumps that convey the aroma into a single tube to the exterior. Alternatively, it can be assembled with a single vacuum pump or without any vacuum pump, using instead direction aspiration, or manual selection prior to the selected test or aspiration.

A display container for displaying an aromatic botanical specimen includes: (a) a container body for enclosing the botanical specimen and scented air having a scent of the botanical specimen; (b) at least one scent discharge port in the container body; and (c) an air pump coupled to the container body and operable to discharge the scented air from within the container body to the environment through the scent discharge port.

A storefront shelf can have a shelf front, a shelf top, a shelf bottom, a right sidewall, and a left sidewall. The shelf front includes a transparent barrier, one or more product exit apertures, one or more product movement apertures, and a set of restocking components. The transparent barrier permits shoppers to view shelf contained products and, when closed, inhibits extraction of any of a set of shelf contained products except through at least one product exit aperture. Each product exit aperture is an opening in the shelf front sufficiently large to permit one of the shelf contained products to pass. The product movement apertures are each opening in the shelf front sufficiently large to permit a hand of the shopper to pass and to thereafter manipulate positions of the shelf contained product(s). The set of restocking components are connected to open and close the transparent barrier. When the transparent barrier is open the shelf contained products can be restocked via the opening.

A retail display kiosk for identifying a saw chain includes a panel, a plurality of slots associated with a plurality of values for a first mechanical parameter of the saw chain, and a plurality of receptacles coupled to the panel and associated with a plurality of values for a second mechanical parameter of the saw chain. A drive link counter includes a hanger and a slider repositionable relative to the hanger, where the hanger and the slider are configured to engage a saw chain, the slider is moveable to a position away from the hanger and the slider that maximizes a distance between the hanger and the slider constrained by engagement of the hanger and the slider with the saw chain, and the drive link counter also includes markings associating different positions of the slider with different numbers of drive links.
