***Official Statement on T-Shirts***
Before you send us an email or leave a review saying something like “I’m really sad that your shirts aren’t soft and they don’t make me feel warm and fuzzy inside or outside and my girlfriend gets mad at me because skulls are scary”. We’ve heard it enough, so please don’t. We aren’t changing our shirts for you. +99% of people who buy them don’t complain, like them, and often buy again. If not, we have a good return policy. You can get soft flowy cute shirts somewhere else and we are cool with that. To each their own. But it won’t have a M/M logo on it. While these shirts aren’t soft enough for all sensibilities, they are very comfortable, fit great, and more importantly they’re built sturdy with heavyweight fabric that will hold up to punishment and won’t show your belly in a slight breeze. If you like our tees, let your opinion be known. Rough shirts for rough people.
