those hats are the original gibson bell hats, and they are pretty expensive in my opinion for just a bit of plastic, but they are the real deal, and does look slightly different and more detailed than the significant cheaper copys, thats why i have choose them.
Please be aware of it that those knobs does not fit on every potentiometer out there, as there are differences in measurements, those will work great for original gibson, but will not fit, for example on the göldo 500k. dont apply to hard if the hat will not fit on the potentiometer as it going to break and will become unusable
