Russian zarinite donuts have a diameter of about 4.5 - 4.9cm.
The hole has a diameter of 8 - 9mm and is therefore suitable for donut holders.
The copper mineral Zarinit supports the sense of aesthetics, harmony and beauty, but also a sober-clear approach is strengthened.
Please note that each donut is unique to its structure and color; therefore, the images are only examples.
