Hard to peel and does not stick well..

I love sticker mule, the communication was phenomenal, and to their credit I was immediately given a 50% off on this order. As suggested, we are also trying stickers versus labels. But unfortunately this product is not what I was hoping for. The stickers are hard to peel, and some don't peel at all. Also, these do not stick well to the printed boxes I am using. I am told the stickers may be too small, but regular clear tape of the same size sticks perfectly. This product would work well for other applications, unfortunately not mine.
