Pure Manganese Metal Cube - 10mm, 99.97% Density Mn For Element Collection & Display

For the science enthusiast or collector! This is a solid cube of pure manganese metal, measuring 10mm (about 0.39 inches) on each side. The purity is extremely high - 99.7% minimum. It's got the element symbol 'Mn' and info laser-engraved on one face. A heads-up: manganese is naturally brittle and crystalline, so small cracks or surface imperfections are normal and not a defect. It's a really cool, tactile piece for a periodic table collection, a desk curiosity, or educational display. Not for chemical experiments - just for admiring and showing off a pure element. A unique gift for the curious mind!
