not too great
The charm maker is clearly not a chemist.  The charms look similar and only the most boring elements have been picked.  There's very little selection.  Mostly N, Mg, H, &amp; F, &amp; B.  Boron, really now?  Who uses Boron for anything except making Borax?  No Pb, Pu, Au, Pt, Po, Ir, Os, Gd or any of the more exciting elements.
