It's not a lunar landar, as other-worldly as it looks. This is a typical T4 enterobacteria phage, carefully crafted from pewter to be an exceptionally detailed, delightfully unusual piece of jewelry. Look closely and you'll see the vertex capsomeres, capsid proteins, whiskers, dsDNA, kneecap domain of long fibers, short tail fibers (spikes/pins), and more. It measures 1 inch high, and comes on a 28 inch gunmetal chain. The chain is fully adjustable - the clasp can be latched on any link.
