good, but look out for the black border

the magnets are good, exactly as advertised, and in the dimensions stated when i was prompted to approve artwork. this is my third time ordering custom magnets. both times prior, i created a "sticker" out of an iPhone picture, and turned it into a custom magnet. both prior times the outlines of the image were white. however, this time, they are black border which does not go well with the images i uploaded. it was black in the proof too, so again i wouldn't consider this a StickerMule issue but please be aware of this. i'm not sure if this is due to an iOS change or why the borders were white the prior two times and black this time when i did the same process.
