Abstract: Presented is a device having a unitary body molded from synthetic resinous material and including a base member having a central mounting recess on its back side for receiving the mounting stud of a suction cup. On its front side the device is provided with a multiplicity of rows of spaced elastically resilient “prongs”, or a multiplicity of “tuft” like projections each formed of many different thin filaments, or a multiplicity of “rod” like projections the distal ends of which are semi-spherical or “rounded” and useful for applying deep massaging pressure to the skin for stimulation thereof. Integrally formed on the base member are mounting flanges having integral mounting lugs and mounting apertures for detachably interconnecting one such device to a similarly constructed adjacent device to selectively form a specifically arranged configuration or array embodying a multitude of the devices.
