From the Bench
Worth reaching for on pressured water, where a polished bead reads as a bead and a mottled one reads as part of the insect.
On the Metal
No tungsten bead is pure tungsten. Pure tungsten is brittle at room temperature and cannot be drilled and finished at this scale, so every tungsten bead on the market is a heavy alloy. Ours runs 95% tungsten with a nickel-iron binder, which is the high end of that range. You get the density without the brittleness.
