3M Yellow Silicone Pads
The 3M consistent Pad . This pad is reliable in how consistent it plays as it wears down. Unlike many of the other pads that have a sweet spot once they are broken in, this pad is as good when you first swap it into the yo-yo as it is just before it is worn down to the core.
19mm Outer Diameter, fits most of the modern metal yo-yo.
C size bearing.
