I have some comfort fit rings, but since my knuckles are too big, the sharp edges still touch my knuckles. Only rings with extremely rounded edges (basically cylinders) do not hurt my knuckles.

Hmm, can you show me your ring so that I can see what a 4 mm height ring looks like? I could not find ring heights because search engines indicate width instead, even when I search for height.

No, I want the inside of the ring to be flat. I only want the edges to be rounded.

The height is important because the more height it has, the more comfortable the rounded edges are. With a ring with round edges and a height of 1 mm, the edges still feel like a knife, so it is important that the height is large enough.

I am talking about the height, not the width. What you said is the width, but I want to know the height. So, what is the height of your metal parts in your ring? Here is an image of the three measurements:

It is not about the ring size but about the height of the metal part. The circle opening in the ring is the ring size.

I edited the post to add an image of a similar ring design. You can look at it.

Okay, I meant literal half cylinders that are attached to the ring so that the main band has multiple curves from these half cylinders. The edges should also have bigger cylinders in them so that the ring is comfortable to put on and take off, and so that the the small and big cylinders have the same height in the top. This is what I want as the ring design:

• Total width: 10 mm
• Total height: 3 mm
• Width main band: 4 mm
• Height main band: 2 mm
• Width middle gray cylinder: 3 mm
• Height middle gray cylinder: 1 mm when cut off in half or quarters so that the half cylinder can be attached to the main band
• Width edges pale copper cylinders: 3 mm, should be attached to the edges
• Height edges pale copper cylinders: 3 mm because the extra 1 mm should match the height of the middle gray cylinder

Is this more clear, or should I explain more?
