Ripeng 14 Pcs Metal Element Cubes Density Cube Set Element Periodic Table Pure Tungsten Cube, Titanium, Bismuth, Aluminum, Iron, Copper, Etc for Element Collections Gift Hobbies Lab Material(15 mm)

A great desk trinket would recommend!

Have them at work as a curiosity piece (s). Well made examples, each labeled.

I got the 15mm set and these look like they were nice when they left the factory. Printing is consistent enough front and back. Unfortunately, the cubes were just loose in their plastic box so they rattled around chipping, cracking, and scraping each other up in shipping. $160 worth of cool product destroyed for want of a $0.01 piece of foam.

16mm is a good size
