The cosmetic unit has two partial units, each comprising a receptacle for receiving a cosmetic substance and a closure cap by means of which the receptacle is closable. The two partial units are inter-connectable by means of a coupling member engaging with the two closure caps. Each closure cap has a cap recess, extending in the direction of a central axis, on the axial front end facing away from the receptacle of the corresponding partial unit. The coupling member comprises a central portion with two axial coupling projections being formed thereon wherein each coupling projection engages with one of the two cap recesses when in the assembled state.
