In original case, as new.
Asking $75 delivered.
I purchased this recently on IIS as a trial on the solar white light set-up.
(To replace the traditional Continuum filter). Unfortunately the outside diameter, although fitting the usual 2" eyepieces/ focuser did not fit the internals of the Baader Cool wedge (!)
When fitted to the eyepiece holder it worked very well.....
