Black Teflon washers in 4mm 5mm and 6mm 8mm

These are the standard washers used on Teac, Tascam and FOSTEX recorders, they are annoyingly difficult to find, these are NOT the same as ones used on toy cars and boats as are thinner, these must cost pennys from some factory in Japan but I have been unable to locate them for my own use.

I sometimes have to break a machine just to get a few of these, the larger cheaper types are ok for 'padding' use, for example on the capstan shaft when the bush falls to pieces, but in most cases you need these.

letting a few go from my personal stash.
