Mason Pearson
Mason Pearson, the company that made, and kept, a name for itself with a boar-bristle brush, has been run by the same family for four generations. The brush’s design has changed little since the original was created in 1885. It still features a soft rubber pad (thought to be easier on the hair), which might not seem like the biggest deal but was pretty much hair-care heresy in the late 1800s.
Volvelle
A volvelle or wheel chart is a type of slide chart, a paper construction with rotating parts. It is considered an early example of a paper analogue computer. Volvelles have been produced to accommodate organization and calculation in many diverse subjects. Early examples of volvelles are found in the pages of astronomy books.
Diplomatic bags
A diplomatic bag is an envelope, parcel, shipping container or any other kind of receptacle used by diplomatic missions. As long as it is externally marked to show its status, the bag has diplomatic immunity from search or seizure, as codified in article 27 of the 1961 Vienna Convention on Diplomatic Relations. It may only contain articles intended for official use. It need not be a bag. In fact, no size limit is specified by the convention. It is often escorted by a diplomatic courier, who is similarly immune from arrest and detention.

Eyemo
Designed and first manufactured in 1925, the Eyemo was for many years the most compact 35 mm motion-picture film camera of the hundred foot capacity. Its small size and ruggedness made it a favorite choice for newsreel and combat cameramen (it was used through the Vietnam War, and the War Department issued special manuals for it), and also found use for fiction and filmmakers whenever a portable, rugged, and inconspicuous camera was needed. The Eyemo is still in use by some filmmakers. It is often used these days as a "crash cam" for filming dangerous stunts and explosions, and shots in which the camera must be dropped from a building or other elevation.
Mystery clock
Mystery Clocks are clocks where the hands seem to float without any kind of working mechanism.
