Defective backing?

Well…I have ordered A LOT of stickers from sticker mule. They are always great. I LOVE how these turned out. The hologram is bold and contrast is great. Unfortunately, I tried to take the backing off of 2 of the stickers and both were extremely difficult to remove. On one the paper backing split and on the other the actual sticker split. I ordered these to give away for free at a show so it’s not worth contacting customer service, but I would recommend checking the backing on any stickers you order. I feel like this was just a bad batch because I have not had this experience before, but wanted folks to be aware.
