Not alphabet blocks.
Well they're not alphabet blocks. These cubes are beautifully machined, pure elements. With their name, and symbol, engraved on one face. I have the other small set that this vendor offers, and the precision is so high, that they can be laid on a table, and you won't see one higher or lower than another. This is a terrific offering. Although I have to admit the prices are high for the casual element collector.

Very Nice Cubes, But Not Well Packaged
The cubes themselves are well-made. They are also packaged in a cute plastic test tube. The problem is that two cubes, W and Bi, got stuck in the tube. I eventually got them out with a bent paperclip, but this unfortunately scratched the Bi. The most surprising thing about the cubes was how heavy Nb seemed! It seems quite light as earring wires, but as a cube it was the 2nd heaviest one. Still fun and recommended.
