Hi.
I recently puchased a 46mm B+W NL-3 Close-up filter for my 20mm from an ebay supplier.
They actually sent me one that was called "Slip-on" ie it was 46mm, but not a threaded one. I did a deal with him and he sent me the correct 46mm threaded one, and I kept both.
I have no use for this "slip-on" filter, or even have any idea what would use one, if anyone else does and wants it, then I will send it to them for £5 (I am assuming these things go for around £20+ the same as the 46mm Threaded one would do!)
