Business Leather Factory System Planner, Bible Size - Color: Black - Material: Leather - Type: Bible I purchased this online about two years ago. I tried putting in refills, but the ones with belts didn't suit me, so it's been sitting in a drawer. It seems to be a discontinued product. I forgot the ring diameter, but based on my measurements at home, the inner diameter is around 20mm. There is no box. It will be shipped in a paper bag + zip lock bag + bubble wrap, via Takkyubin Compact.
