I think they're called the NexGen Pro series -- nice colors and graphics, chips are lighter weight than prior NexGen chips (the Pro version are not slugged, IIRC), but they are slippery in stacks. Not a bad choice for a low budget set.
Just read this line from the ad "just moved from Las Vegas and this set is 1 million dollars of casino grade retired chips." LOL. They are not casino grade or retired chips. What is it with some sellers that just straight up lie in their ads.
