Ethan was very attentive from start to finish. I was surprised by how fast they finished my 600 kiss-cut sticker sheets. The cmyk colorspace was a bit of a learning curve for me, but I am glad to have taken the chance with this manufacturer. I am happy to have found this manufacturer- they are easy to work with, time efficient, and produces wonderful stickers. Looking forward to working with Guanzhou Chaoya Printing Technology Co. again in the near future!
