What an awesome shirt! I’m a chemistry teacher and will be wearing this tomorrow. It looks even better in person than it does online. The seller is very attentive and communicates wonderfully. I highly recommend both the shirt and the seller. Thank you so much!

My chemist friend absolutely loved this hat. So much so that he asked for the link so a collaborator can get one of their own!

As an inorganic chemist, it's so nice to find chemistry-themed hats that don't have caffeine, dopamine, DNA, or serotonin on them. 10/10

Turning Real Science into Cool Designs

Needing a break from pandemic teaching, I designed a custom hat for myself to show off my chemistry identity. I shared a picture on social media, and next thing you know people were asking me where they could buy their own. Since this is not a full-time thing for me, I looked into print-on-demand and here we are!

My aesthetic uses a minimalistic clipart style to convey real scientific content. I actually use my designs often as a teaching aide!

I'm an organic chemistry professor who was looking for real science-based merch and couldn't find any... so I started designing my own art!
