Quick easy service, colors not quite right

This was my first time ordering with Sticker Mule, and I have to say, their quick proofing process works very well. I submitted my artwork, and within an hour I had a digital proof. After approval, it only took about 2 days for 150 buttons to reach my house. While the color was quite a bit darker than what I was hoping for, the actual button construction was high quality, and the ability to swivel the button to line up the pin on the back was great. After talking with customer service about the color issue, a new proof was provided and a new order of buttons arrived to my door within 2 business days. I am very impressed with their customer service and correction of the first run of buttons.
