A review for Circle stickers by Branden Hall.
Overall I was really happy with my stickers. The colors don't "pop" quite as much as I was expecting, but I believe that's mostly due to the thin lines and the natural difference between transmissive (monitor) and reflective (printing). The actual sticker itself is obviously very high quality and sticks extremely well. Split-back would have been nice, but they're still pretty easy to remove from their backing.
