The ProtoStar was designed to be a plastic yo-yo that played as well as a metal one, produced with the help of World Champion John Ando it features a very wide gap and tapered catch zone.
This is a stock picture. This example is not only new in the original sealed case, but with shrink wrap around it. Opening it to photograph would lower the collectible value.
Protostars can be converted to Responsive play easily with a shorter threaded axle and half spec C bearing, but come stock Unresponsive, dead play.
This one is available. I will consider all reasonable offers. If interested, please email me, whistler42@swcp.com .
