Matching socket set to a holder

[Zeroek]

I have a Mac Tools MT5Y socket holder. No sockets of course. The supposed set of sockets that is supposed to go into that holder according to the MAC website is set SMMUD106T. 1/4". Well when you go to search for that set it isn't on the website or catalog. Just the socket holder and it says that part number for the socket set. So I'm curious if anyone has this set at home or work and can tell me what sockets will fit into it. It's strange because the socket holder don't taper. Almost like all the sockets are the same size at the drive end. And it's a metric set.

I figured this was for a universal set since it didn't have a taper. From Ebay
