OSMIUM 10mm SOLID METAL CUBE PROTOTYPES (LAST ONE!)
Only one prototype cube left!
Osmium Cube Prototypes
We have two prototype cubes of pure .9995 osmium! These are extremely difficult and expensive to make. It's your chance to own the densest element in the universe. Each cubic centimeter is pressed into shape with 60 tons of force. Each cube weighs 22.5 grams or more!
With its signature blue tint and insane density, it's a must-have for the serious metal collector. It's the first time we've offered Osmium as a cube because generally, it's too difficult to work with.
These are the only two prototypes we have!
Polar Metals seeks to spice up your life with interesting and unusual metals in unexpected ways.
Laser engraved. Lasts forever. For true metal lovers!
* Each solid cube comes with a crystal cube base for FREE.
