Creator Review
This is my image, I'm very fussy! I created this little black cat, he is my avatar and logo, so this had to be good. This is a great quality product for the price, the movement is good but the finish is excellent. It exceeded my expectations. Perfect, a very glossy finish over excellent printing. The colours are rich and strong. I was very impressed.
