Really like this shirt! It caught my eye, and I knew I had to have it. It gets lots of comments from friends. The shirt seems to be a good quality tee and the printing was well done. It was delivered promptly, arriving in about a week. I’ve purchased 3 or 4 shirts from Knarly Tee’s and have always been pleased.
I purchased Divde by zero for a gift and it was perfect! She loved it and the color was perfect also! Thank you!
