I’ve been seeing images like this making rounds. I understand this is just a snaffle and the “it’s a kind bit” and “I have soft hands” stuff. Save it. It’s not about this bit being rainbow. It’s about the majority of the people who would buy something like this are people who buy things because they are pretty and make them look good instead of thinking about what would be most comfortable for their horse.
This trend may start out in just snaffles, but it could easily make it’s way up to something much worse. Nobody would question it either because all they would think was “pretty colors” or some idiocy like that.
