A device is described that possesses an overall shape that comfortably fits into a user's hand, and in particular, can be manipulated by the fingers. The device is fabricated of a pliable material that readily can be manipulated by manual pressure, yet holds its equilibrium positions absent pressure. The device has convex/concave surfaces which can be inverted to provide two stable equilibrium positions. The surfaces of the device may have different textures, such as smooth and ridged. The material of the device can have various colors, and also may be phosphorescent. Floral, fruit, spice and other scents may be added to the material such that the scent emanates from the device as the user manipulates the device.
