Listing is for 2 pieces of new old stock Russian made axial Teflon dialectric capacitors 0.018uF. 25 x 14 mm. They are hand matched to 1% tolerance of each other. 

LCR meter reading of randomly selected part, phase measurement given to represent closest to optimum 90 degree accuracy.

They have been marked to indicate inner and outer foil, but I have found this to vary from part to part, so best to check manually, e.g. with an oscilloscope probe and seeing which end is better to connect to a low impedance.
