You better check every holographic sticker

I love the Holographic stickers but you better check every single one you order. For my last order, of my 100, 40% of them have a vertical line down the front, from one end to the other, and several others have light scratches on them. I'm not really sure how I'm supposed to sell them that way. CS said that happens and it's not noticeable, but I disagree. They were nice enough to replace the 40, but 8 of those replacement again, have the vertical line down the front. This is my best selling sticker, so I'm going to have to figure out an alternative, because clearly, they don't QC these, which really sucks.
