Abstract

The present invention is directed to a substance delivery system comprising a three-dimensional structure. The structure has outermost surface features an d spaces between the outermost surface features for containing a substance. The substance has substantial resistance to flow prior to delivery to a target surface and occupies the spaces of the three-dimensional structure. The substance is protected from inadvertent contact with external surfaces. The substance remains protected until the three- dimensional structure is deformed and the substance is exposed to contact an external surface.
