Created this to compliment my Sword and Shield cosplay. This band is constructed in two pieces that slide into one another. This allows the bracelet to fit on your wrist without much difficulty.
It can be resized up and down pretty reliably. Just make sure to scale both parts by the same increment.
The opening diameter measures 2.5 inches (63.5 mm) across.
The entire band measures approximately 82 mm x 82 mm x 66 mm.
