Customer photo review of Element Cube Subscription

I love cubes, it's one thing to study the periodic table, it a whole other ballgame to have the elements sitting on display. So glad I found Engineered Labs...this is a truly original treat.

I can not express how blown away I am with the quality and look of the D-Day barbed wire pieces. They make perfect gifts for an history lover. I have actually ordered multiple times because I keep thinking of people who would love them as gifts. each one is unique and beautifully crafted.

Customer photo review of Uranium Element Cube (2inch Autunite)

I am thrilled to finally have my own "forbidden chicken nugget" sample. I recently started collecting uranium glass and love science, so this is a cool addition to that once I secure a display case for everything. The cube is well-made and turned out to be much bigger than I was expecting upon seeing it in person. My family is excited to start collecting more of these neat pieces from Engineered Labs!

Customer photo review of Heritage Periodic Table: Collector's Edition 85 Elements

Genuinely kicking my feet looking at it. It’s so cool. With the mercury you can see it move in the little ampule when you move the table side to side. Though, two of the elements are a bit off centered (the cesium and Dysprosium) so it kinda covers part of the name, but I don’t mind too much. It comes with a little certificate and a list of where the elements came from n stuff PLUS a little baggie to store it in. It kinda does have some weight to it. It’s such a beauty, I love it soooo much and if you’re thinking of buying it, DO IT. ITS SOO WORTH IT.

Customer photo review of D-Day Barbed Wire Artifact Display

This is such a great piece to have. It’s both stunning and humbling. Every WWII movie will feel a little different now that I have an actual piece of history right next to my tv. This is such a great gift for WWII buffs.

Customer photo review of 2" Movement Cube

I really like this piece, but I was hoping the clock face would have the hands on it, in any position. The one I received did not have any hands. It’s still interesting to look at and ponder. I’m on the waiting list for the uranium cube, hope it is back in stock soon!

Customer photo review of Element Cube Subscription

Absolutely love my Engineered Labs element cube subscription! Every month feels like a little science Christmas. The cubes are beautifully made — crystal-clear acrylic, perfect laser etching, and that real element sample suspended right in the middle. This month’s Beryllium cube is stunning. It’s the kind of thing that makes you stop and actually look at it every time you walk past. The packaging is solid, the quality is consistent, and it’s become one of my favorite monthly rituals. Highly recommend if you want something that feels both educational and collectible. One suggestion: It would be so cool if each cube came with a small fact card. Just a couple of interesting tidbits about the element (discovery story, unique properties, cool uses, etc.). Would make the unboxing even better and give people something fun to read while admiring the cube. Keep doing what you’re doing — these are excellent.

Customer photo review of Cesium Element Cube

Finally get to experience the most reactive metal and the least electronegative element from the safety of an acrylic cube (and its low melting point makes it fun to play with as a bonus)! The minor downside is that the cesium is only ~99% pure as some of it is stuck to the glass ampoule and can't come off no matter how many freezing and melting cycles I do (see photos). If it were 99.99+% pure it wouldn't stick to the glass and would've been more fun to play with.

Customer photo review of Trinitite (First Atomic Bomb)

After a road trip in May, going from Los Alamos, seeing a sample of Trinitite in Albuquerque nuclear museum and then stopping at the Trinity test site on route to White Sands having the opportunity to own something like this was a dream. After receiving it, it’s better than I’d hoped for, it’s an amazing piece of history that is presented beautifully. A incredible talking point that gives me another opportunity to bore people with my holiday.
