#FBF Long Sleeve T-Shirt (Unisex Adult)

BE A SCIENCE AMBASSADOR! Elevate awareness about the scientific 'facts of life'.

Flash back to the first day of your existence by wearing Contend's #FBF t-shirt.

The t-shirt contains a graphic of a Carnegie Stage 1 human being (it also happens to be our logo), when a human being begins to exist.

Obviously, it is not drawn to scale! A sexually reproduced human being begins to exist at the beginning of Carnegie Stage 1a, and measures .1 to .15 mm, and weighs about .004 mg, by the END of Stage 1 (Carnegie Stage 1c).

YOU used to be a single-cell human being too!
