We have ordered multiple round stickers from Sticker Mule now and have been pleased with the quality of all the stickers. 

Both the rolled and diecut stickers have excellent color, and texture.  The rolled stickers are definitely thinner than the diecut, but for their purpose they will be perfect.

I did compare prices to some local printers in our area and found Sticker Mule to be competitive if not less expensive and their online process to be easy.

Excellent Quality
