Tantus Super Soft Silicone C-Ring
This ring is clearly good quality. It's entirely made from Tantus's soft, platinum silicone, and is designed for comfort with a thick band and rounded edges. My partner didn't end up liking it, unfortunately, because it didn't fit him very well and the silicone doesn't stretch very much. For folks who fit it perfectly, or who are looking for a snugger ring this might work better for them.
