According to People Magazine she is the "QUEEN of CROWNS"

These tiara and crown cases are great! They have a transparent front to show your beautiful crown. You can carry them with their metal swivel handle or by the shoulder strap which has a total strap length adjustable from 26" - 50". On the inside, there are velcro straps to hold the crown snug to the center cylinder to protect the crowns while they are transported. I fits all crowns or tiaras that have a diameter up to 10 inches and height up to 10inches.

There is also the option of a silver 2x1 inch personalized nameplate for your case.
