Yes they do , I have the 3.2 , 5.2 , 9 , 12.5 mm's , untill I sold the 21mm to Trevor and they are all good eyepieces , Vixen Lanthium clones and very over looked .
I have not a clue why they have the 3.2mm on then ??

.
Maybe the Ed lense inside is 3.2mm thick ? or 3.2mm from the focal plane ? or .... or ..

Enjoy yours , Trevor what ever the reason.
