5 out of 5 starsThis shirt is great! Super soft, size seems true, and the image is clear and centered. Not sure how it will hold up in the wash, but I’m always concerned about that so no big issue there. Bought for a biochemist in my life and he’s going to love it! It was really difficult finding something this specific and I’m SO glad I stumbled upon this shirt!!

5 out of 5 starsTurned this long sleeve into a crop top, and it really pops with my outfit. Worth waiting for the shipping.

5 out of 5 starsI got this top and turned it into a crop top because they did not have one at the time. It looks great with the bright yellow colors and the letters. It is always a great conversation starter with my fellow scientists, colleagues, and surprisingly non-science lovers. Support was great, and I will come back.
