Mezz wx900 and OB2+ shafts sell/trade

I have a OB2+ shaft: 5/16 x 18 thread

Mezz wx 900 shaft: 5/16 x 18 thread

Both are in New condition. Make me a reasonable offer on either of them. May be open to trade for a nice cue case 4x8, a players HXT ld shaft, or Mezz WD 700 shaft in same pin 5/16 x 18 or 3/8 x 10 thread
Please justPM me if interested thanks

It is not the mezz United joint. Unless the United joint and 5/16 x 18 thread are interchangable? I don't own a mezz cue any longer so can't try it. It is standard 29'' length. Please PM me if still interested thanks.
