Tool search: *Really* small circlip pliers?

Hi all-

So I'm restoring a couple classic cassette decks, and in order to get the pinch rollers off I need darn near microscopic circlip pliers. Attached are a couple photos. Those shafts are about 2mm diameter...

I went to McMaster and even they don't have anything small enough. Any hints to where I can find a circlip tool to deal with this? Thanks, as always.
