A sampler for delivery of microencapsulated liquid fragrance material is provided that comprises at least one treated paper sheet defining an enclosed cavity. The paper sheet is at least partially treated with a volatile containment treatment, wherein the volatile liquid containment treatment is water-stable and organic liquid capsule fill-stable. The enclosed cavity is substantially completely defined by treated portion(s) of the sheet. Microcapsules comprising microencapsulated organic liquid capsule fill are disposed within the cavity.

A method of making a sampler for delivery of microencapsulated liquid fragrance material comprising a) printing a substrate sheet with release coating, b) applying a volatile liquid containment treatment which, when cured, is an organic polymer, to said substrate sheet and overlying at least a portion of said release coating, c) allowing said volatile liquid containment treatment to cure to a state so that it is liquid water-stable and organic liquid capsule fill-stable such that said substrate sheet having volatile liquid containment treatment thereon allows the transmission of water moisture vapor therethrough, d) applying an adhesive generally overlying the area corresponding to the release coating and overlying at least a portion of said volatile liquid containment treatment, e) applying microcapsules comprising microencapsulated organic liquid capsule fill to said substrate sheet such that they are disposed on at least a portion of the volatile liquid containment treatment, f) folding said substrate sheet so that the adhesive and portions of the substrate sheet define an enclosed cavity having said microcapsules disposed therein.
