Holographic stickers seem less consistent

I place orders from sticker Mule all the time. I think they do quality work and I am generally super satisfied. The hologram stickers seem to be hit or miss though. I always add a note to please adjust the colors if needed to show contrast. On this particular sticker, it basically just looks silver. The pink stripes barely show at all. Lesson learned…use dark colors only. Will still order again, but probably not the holographic variety.
