Hi new followers from Sensoryseaturtle (which, by the way, is one of my favorite blogs on tumblr)!
Since you’re all here, I might as well finally post a review of at least part of my most recent Buckyballs order: Buckyball colors. Here they are combined with my usual silver ones:

Two sets combined is just enough for an icosahedron, a 64-ball cube, and an 8-ball cube! Sadly, though, it’s impossible to make an icosahedron out of two colors and make all adjacent sides be different colors from each other. This should have been obvious due to the five-triangle points, but I still tried.
The Buckyball colors are actually not quite the same from a sensory perspective as silver Buckyballs. The coating that gives them their color slightly weakens the magnetic attraction and makes the balls a bit less slippery, which makes them sort of “crunch” against each other when you’re squishing them around in your hands. This can be good or bad, depending on what sensations you like! I sort of like the crunchy sensation but other times I prefer the silver ones.
I really like Buckyball products as “at work” toys because they are very satisfying while remaining professional-looking. They’re a bit pricey though, and are NOT for children or adults who tend to put things in their mouths a lot, as swallowed magnets of this level of strength can send you to the ER. I keep them in my office where they’re safely out of reach of kids and pets.
I also got an order of Buckycubes (basically, square mini-magnets that actually act TOTALLY DIFFERENTLY from Buckyballs) and Buckybigs (eight really large magnetic spheres), but I’ll leave that for later.
