Alright let's be real... I had to do this. How could I not put this on a shirt? It's traditional to render images of Satan in Christian art to remind ourselves that he is real and that "we wrestle not against flesh and blood, but against principalities, against powers, against the rulers of the darkness of this world, against spiritual wickedness in high places" (obviously true). He is shown wearing a mask with other appropriate motifs. HOWEVER this is a warm up for a more explicit 'angel killing satan' shirt and, as I'm worried it could be misinterpreted by normies (it does say 'the adversary' at the bottom though) this will only be available for [a limited time]. That's how it is.
([READ THIS] a note on sizes: I used to advise on sizes but there is just too much variation between people. I'm about 6'2, and skinny, and I wear a medium. The medium is pretty large, but for some guys it's not big enough. Honestly the only way to make a safe bet is to check out the sizing guide below and measure yourself or one of your shirts that you have that fits you well. I can't do returns because they're all made to order so, it's not like I have a ton of them all here at the studio. If you want to order a bunch I'd probably advise getting one and then seeing how it fits and then going for more.
On my end, the data I can give you is that after advising that if you're torn between the medium and the large to get a medium, it worked out for most people, but some guys have bigger arms or actually needed the large so, like I said, basically gotta measure yourself.)
