Chemistry of Life (8 Pack)

A complex molecular structure blended with a classic atomic orbital model, the building blocks of life drawn as ornament. It is for the scientist at heart: intellectual, precise, and unembarrassed about either. Size & Placement Eight 2.36 x 2.36 inch tattoos per pack, bonding well with the forearm, wrist, or behind the ear. Lab mates make an obvious sharing plan. Semi-Permanent Ink, No Needles The ink is semi-permanent: it synthesizes within 24 hours, holds its bonds for up to 10 days, then decays cleanly. No needles in the experiment.
