Product Overview
The unique and the extraordinary Cobalt Mini Cube! Our Mini Cubes are the safe, easy way of viewing and displaying element samples – they’re both affordable and hardwearing. Perfect for educational purposes or simply to collect.
These cubes are made from high-quality optical resin and contain 99.99% ultra pure Cobalt metal balls, set inside. Each element sample is carefully selected for both aesthetics and educational value. Some of these have one larger pellet of Co, some have three or even four smaller ones. If you have a preference please let us know and we will pick the pellet count you want if current stock allows.
(We also offer these same Mini Cubes with a range of different element samples, including those that are normally too toxic and dangerous to handle – but are made completely safe when set into this special resin. View the full range here> )

There may be the odd imperfection (tiny bubbles etc.) but every effort is made to ensure they look spectacular and provide an accurate representation of their properties.
Please note there may be a slight yellow tone to the resin over time, all resins will yellow slightly with time. Keep them out of direct sunlight to help prevent too much yellowing.
