This is a wider version of the File Mark wedder that I have been making for nearly 10 years now.
The width has been increased to approximately 6mm wide.
I am more than happy to customise these rings according to individual requests.
The original File Mark wedder is about 4.6mm wide.
Some people prefer a thinner ring, others like more substantial wider rings. As each is hand made new, the width can change accordingly.
This very ring is at e.g.etal.
