A reusable casket includes a metal casket box having an opening at one end and includes a panel section rotatably attached to the casket box which is closeable to enclose the opening and openable to allow longitudinal movement of a casket insert into and out of the casket box through the opening. Temples or a retention strap are provided for attaching the protective eyewear to the head of a user. The swim fin preferably comprises a staged closing during movement in the second direction, in which the opened flipper blade provides decreased flexion as the effective surface area is decreased. A display device employing this film with a multi-dimensional grating pattern provides improved light emitting efficiency and enhanced image quality.
