Nice buttons

I really like the size of these buttons. However, when I received them there was a grey spot on the lower right of the pic that wasn’t on the pic I submitted and I didn’t notice it on my proof. I had put a QR code on my pic and Sticker Mule did warn me that it may be too small. So I made it bigger and sent in the pic again. The proof I got back said the QR code was still too small. At that point I checked go ahead and print anyway. When I got my buttons in the mail, not only is there a mystery grey spot on my buttons, but also the QR code does not work (I take responsibility for that one though). These were made for a country music artist/merch and now I’m not going to be able to use them. These could be really great. Just this one time I’m not 100% satisfied and I’ve placed many orders.
