Review on Srixon Soft Balls Yellow Dozen by Thasapon Bowers

I only got them today so I haven't used them. I doubt these are the latest "soft feel" balls shown on the site I bought them from? There is no SCP. for the ones i received it is 4907913152221. The reason for my question is that the photos describing the balls in Revain online showed a very similar box lid except that in the top left corner was a red banner that said was "NEW". As you can see this is not on the box I received. One of the other product descriptions mentions a "Previous Generation Ball" so I am wondering if I received a previous generation ball and not a NEW one as expected. Many Thanks
