The horns are far sharper then I expected. They could easily scratch or even cut someone if not careful. Unfortunately, it's made of sterling silver, so it will definitely turn my finger green and more than likely yours over time. Though I believe there may be a way around that, I still have to look into it.
It is somewhat adjustable since it doesn't connect all the way around. However, I didn't have to adjust it much since I have relatively smaller hands for a guy. If you're a man's man (I am not), I don't think I could recommend it since it would likely be too small, but that depends on what finger you wanting/willing to wear it on.
Overall, you get what you pay for, which is a cheap ring that looks neat and shows off your love for Digimon. I like it enough that I am thinking about getting the MetalGarurumon ring too. If you're interested, I got it off Amazon.
Edit: some grammar
