Black spots are possible, but they are washed away.
Very, very beautiful model. I ordered 3 sets at once, 2 of them came in the same package. And the third one was different. Most of all the devices were perfect, but there were also those that had black dust, which at first glance looks like a defect and cannot be washed off. But I tried to wash everything thoroughly, and the foam did it. And it turned out not to be a defect, but a dust stuck during production. There are 2 options in the photo, one has a perfect device, and the second one has a device with dust stuck before it was washed.
