Creator Review
Overall very high quality , nice and neat. The fabric feels very comfy, durable yet very natural. The print itself is very detailed (black is not 100% black, but that's OK). 99 out of 100.

This sweatshirt is super comfortable. The colors are exactly what I expected and the writing blends in nicely. The quality is better than I expected though. The printing came nicely; I get compliments on it all the time. I use the shirt for marketing and it does the job :).
