Like Garczar said, it could be literally any tip, personally does not look like a Kamui to me. People have been putting those clear pads under tips as they like the look, personally I hate what they do to the hit.
Acrylic disk pads are much softer than fibre or carbon fiber pads. When installed they protect the ferrule without compromising the hit. This material glues on best with either ZAP or Tiger CA adhesives. Set of 3.
