9 PCS Element Cube Set 10mm Density Cubes Up to 99.99% Purity Daily Metal Cubest Titanium Carbon Lead Nickel Iron Copper Zinc Aluminium Tin

This company makes great quality element cubes for collecting. I plan to get as many as I can! At 1 cm each they are small but still fun to collect. Mine came with the lead (Pb) which I was happy to see. For real fun buy this set and another that has tungsten (W). The tungsten is almost twice the density of the lead! I noticed the lead is getting a bit rounded, so I now keep it separate until I receive the acrylic cube these folks also sell. The laser etching on the iron (Fe) looks like it might already be oxidizing which I feel makes it look more interesting. The copper (Cu) is brushed and was very shiny when it showed up but is a bit dirty looking after handling it.

Me funcionaron para explicar densidad y que los alumnos midieran y determinaran por ellos mismos los cálculos. Los recomiendo mucho!

This was a gift for my nephew - he loves science and collects minerals so he was thrilled with this.

Lo bueno: Son muy bonitos y se ven muy bien. Lo malo: No son del mismo tamaño en la foto se puede ver como el de cobre es un poco más pequeño qué los demás, no entiendo por qué si ni siquiera es el material más caro. Lo feo: Parece que incluye una caja pero no es así, viene cada cubito en bolsa individual. La caja de la foto ya la tenía yo.

Although it took way longer than expected (wasn’t aware it was an out of country seller), the cubes were well worth the wait! They were clean and individually wrapped with care! They were exactly as described! Great start to an interesting collection for my budding scientist!! I also wanted to note, since shipping was taking longer than expected, I contacted the seller. They responded fast and professionally! I would definitely recommend this company and will continue to get more cubes from them!
