Ringgrößen
It is difficult to find the right inner diamter. We made a stencil that should helps you to measure the right inner diamter for you.
Comparison with ring sizes could be a little help. Those comparisons are not exact – therefore we don’t give guarantee for that. But you can use it as clue.
