Callaway Hex Tour Soft golf balls available from Costco

Was at my local Costco yesterday and walked by this display. I know Costco has previously sold "special" Titleist and Callaway balls in the past. Anyone know which model of the Callaway line up this ball might be? Right next to these were the last of the Callaway Superhot 55 balls.
I also noticed that online they are selling these balls 4 dozen for $59.99. The description there is clearly a 3 piece Ionomer cover ball:
Features:

• HEX Tour Soft is Engineered with Multi-Material, Multi-Layer Technology that Improves Spin Separation
• Improved Ionomer Cover Creates Green-Grabbing Control

Saw this at our's earlier today...is this a Costco only thing from Callaway?

I saw it to. Less than a dollar a ball. Would like to know if they are good or not
