A shaving kit includes cartridge store for storing at least one spare blade cartridge and a container for storing a shaving fluid like a refreshing or cleaning lotion or a shaving foam. Members of the grasping assembly are shaped to approximate contour of the dental appliance. Cyclopropene amine compounds, enantiomers, stereoisomers or salts thereof are also provided. The handle assembly permits an axial rotation of the cord bundle mounted on the collapsible cord holder in order to facilitate unwinding and prevent entanglements.
