from the inside surface of the annular body 14 thereby creating a shoulder 24 that has a smaller circumference than the outermost circumference of the display item 22 and creating a shoulder surface 25 illustrated in fig4 the shoulder 24 keeps the display item 22 from falling through the upper circumferential surface of the annular body 14 the display item 22 is firmly secured against the shoulder surface 25 by use of a snap ring 32 viewing the annular body 14 from the lower circumferential surface as shown in fig3 the snap ring 32 is adapted to securely fit into the groove 34 the groove 34 is an indentation in the inside surface of the annular body 14 placed a distance approximately the width of the display item 22 away from shoulder surface 25 in a direction towards the lower circumferential surface of the annular body 14 the snap ring 32 has a spring like quality when the snap ring 32 is in a stable state the outermost circumference of the snap ring 32 is larger than that of the inside surface of the annular body 14 the snap ring 32 is adapted to be temporarily tensed or deflected in such a way that the outermost circumference of the snap ring 32 or portions thereof is temporarily smaller than the internal circumference of the annular body 14 the snap ring 32 can.
