Hi. I have been getting part 4175 in black from some 1970s/1980s lots and they
have tiny white speckles in the color dye. I have washed them and it won't
come off. Any thoughts of why they come like this? Anyone else have some? Sorry
I cannot get a close up picture.

Thank you

It's likely that the plastic mixture either didn't separate cleanly from
the mold during a previous color run, or there were residual particles of white
plastic pellets in the injection molding machine when it was made. This is normal,
and not something to worry about.

Cheers ...

Thank you. Should I mention this while putting the part in my store?
