20 Piece Element Cube Set 0.39” Density Metal Cube Set 10mm Up to 99.99% Purity, Tungsten Cube, Bismuth and 18 More for Students Teacher Science Lover Collection&DIY (20)

Excellent quality, and great learning tool for kids! Colors, weight and density are accurate.

My 11 year old son loves these. They are small but fun and educational.

I absolutely love them. I am a big nerd and these were so cool. However it is important to be aware, antimony and lead should not be handled regularly or at all of one can help it. Especially antimony. I did not see anything in the description of the product that makes note of this so be sure to store them safely and away from children or pets.

This is the perfect gift for a science nerd. My kid loves it!

If you know a science, geology or chemistry geek, this is THE gift to give them. Seriously. Who knew some little cubes of metal would make them so happy? I have had this on my desk for a while and my sister saw it and lost her mind. She was the chemistry geek in school. And this set is a better fidget toy for her than anything I could have thought about getting her. It is fantastic to see how different the properties of these elements really are. They are identical in size and that’s about it. Well-engraved and beautifully presented.

These element cubes make for an intriguing collection. Each cube is small but sharply machined, allowing you to truly feel the differences in density. However, without a way to verify, I had to take the stated purities at face value.Though initially novel, I found that the interest waned over time. Unlike rocks or crystals that offer inherent intrigue, these cubes don't hold the same lasting appeal for me. They're more of a curiosity than a practical tool or an enduring source of fascination.

I love this so much!! I've wanted something like this for a while and just never got around to it, so when I saw these I haaaad to get them! I was literally so excited to get these - I'm really bad at science but I love it so much lol. I just think these are so cool - it's really fun to physically feel the difference in weight. I could gush on and on lol but I'll stop. This is definitely a great gift idea for anyone with an interest in science. I'll also note that these came pretty well protected, so kudos for that. Highly recommend!

Looking for a science present?I got this Element Cube set as a present for my daughter in law who is a scientist. I haven't given it to her yet, but I love the 10mm cubes. The cubes are perfectly cut and well engraved. It's a fun "science" gift for any age. Recommended!Pros:-Engraved: Each cube is labeled with element number, chemical symbol, name, and density. (See photos).-Package: The cubes come sealed in an airtight package to minimize oxidation.Cons:-None
