Carbon rings, flat and round, convex (rounded) on the inside – optionally flat or rounded on the outside, in six different widths. The rings are extremely robust and feather-light.
 
 The standard widths are: 3, 5, 7, 11, 15, and 19 mm (19 mm not shown). The corresponding ring thicknesses are approximately 1.6, 1.9, 2.1, 2.2, 2.4, and 2.7 mm. Custom orders are also available in any desired size and alloy of your choice. A stone is also available.
 
 These slim rings are perfect for stacking. They are available in inner ring sizes from 50 to 70 mm. Larger or smaller rings, as well as rings in other widths and alloys, are available as custom orders.
 
 Don't know your ring size? No problem: Upon request, I will send you a ring sizer after receiving your payment, which you can keep (free of charge within Germany; for international shipments, the shipping fee for the ring sizer will be retained if you subsequently return the item). Furthermore, you have the option of trying on the chosen piece during the return period – if the size doesn't fit, simply return it and I will send you the correct size as soon as possible (free of charge within Germany if you subsequently purchase the ring).
