Mine came on time. And I did notice some dark small spots but as I looked closer it was dark thred inbetween the curtain layers. Which is just something that happens.  It does not bother me at all.  They are more of an off white/ light yellow color not white. But it looks good with the other colors in the curtain.  I used them over a adverage sliding door and 2 curtains (1set) was all I needed.
