An item holder mountable by suction on a mounting surface including a deformable and transparent body. The body includes an outer surface, an inner surface, and a periphery extending around the body and surrounding the outer surface and the inner surface. The body further includes a compartment having an opening adjacent the periphery and extending between the inner and outer surfaces for removably holding an item. The body is deformable from an undeformed shape to an actuated shape to mount the holder on the mounting surface by positioning the inner surface of the body adjacent the mounting surface when the body is undeformed thereby forming a cavity between the body and the mounting surface and deforming the body to its actuated shape thereby sealing the body against the mounting surface and forcing fluid out of the cavity to create a suction between the body and the mounting surface.
