31mm. Shank has an opening of approximately 2-2.5mm.
Beautiful pressed Czech glass relief button. Large buttons are great for jewelry focal points (especially Kumihimo), fiber accents and more. They do not have to act as a closure, but can
be strategically placed to make your garment or craft even more
This button has a "black AB matte finish", which means the color on the back is black but the color looks like it varies from green to blue to yellow in different lighting.
