A review for Die cut stickers by Mitch Facer.
UPDATE2: My stickers were sent out after a hiccup with resending them (they included 50 extra stickers to make up for it) and they look much better. Great customer service and they will respond to any problems you have and fix them very quickly.
UPDATE: StickerMule support e-mailed me to say there was a problem with the printer and they will rush me a new set of stickers. I'm excited to see how they look! 2 stars for quick help - I can't wait to see the final product and bump it to 3!
The mockup and shipping were both done very quickly, but I was disappointed with the resolution of the final product. It looks like it was printed at 72 dpi even though I attached a 300dpi image and told them if they needed the vector file to let me know.
I wish there was a prominent warning that they are only printed in 72dpi. other than that the stickers look good, but would have gone with someone else had I known.
