i bought it brand new from ishibashi..
i put it under a bridge light incase they were black and i couldnt see them.. lol.. but to no avail.
this um.. sucks ☹
sorry for the bad quality of the image but you get the idea..
that's a shot of both knobs on different angles for each just to get an idea.
EDIT: i don't know why all those dust particles showed up..
think 'cos i set the camera on automatic and it's a dimmed room..
it did it at a super-quick shutter speed.. 😲
but um, just know, that there's nothing around the knobs to the visible eye lol
it looks like icing or something in that pic.. mm.. icing. 😛
