I was skeptical trying out stickermule, so I decided to take advantage of their sample pack for the holographic stickers, and then they were running a special on the glitter stickers, so I wanted to compare them with each other.  I also bought the vinyl stickers.  I was blown away with the quality of all of these stickers.  They worked with me back and forth via email and sending proofs until it was exactly as I wanted it.  I'm so happy with the whole process. It was so easy.  I won't hesitate to use them again!

Exceptional quality!
