0.39" Element Cube Set 10mm Density Cubes for Periodic Table Collection Up to 99.99% Purity (0.39", 9-03)

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.

Super cool little gift for the STEM kid. Has most of them in it. Will last forever. They are small but when you get them all it makes a nice little display and conversation piece.

The cubes are great quality.There initially was a mistake with my order, but Magerial's customer service took care of fixing it promptly, which is greatly appreciated.

It's a nice set. I purchased a "used - like new" set from the warehouse, and it must have been an older set with lead instead of bismuth. A little disappointing, since it's a gift for my 13-yr-old. It's okay, though. He asked for a tungsten cube, anyway, so I just swapped out the poisonous-brain-damage cube for the oh-my-god-this-is-freaking-heavy cube.

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!

Faced with a cost of approximately $435.00 for calibration standards for an XRF we use these perfectly sized cubes to calibrate our handheld device. Not only are they cost effective, a 24-hour delivery is superior to a two-week delay (Supply Chain issues).In our unique situation the individually vacuum sealed packages mean the calibration standards are always clean, free of contaminants: overall, perfect.

Pretty neat but pretty small cubes.

These nine element cubes are great for science learning so that kids can hold an actual piece of copper, lead, iron, etc. They come with a little plastic box, so that's good to keep them together. NOT for little kids as the cubes are very small. I purchased these for a very bright and careful 8 yr. old along with a book and poster about the elements.

As the owner of Devil n Dove, I am thrilled with the 9 PCS Element Cube Set. These 10mm density cubes are up to 99.99% pure and include a great selection of metals like Titanium, Bismuth, Carbon, Nickel, Iron, Copper, Zinc, Aluminum, and Tin. They are perfect for our metalworking projects and add a unique touch to our collections. The high purity of these cubes ensures excellent quality, making them ideal for both educational purposes and DIY projects. If you need reliable and pure metal cubes for any purpose, this set is a fantastic choice. Highly recommend!

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

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.

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