Here's some paperweight stocking stuffers for chem students and teachers, general science geeks, geeks in general, and people who just like to call it like it is. Metallum Gifts makes their periodic paperweights and desktop decor from .999 pure titanium or copper. No bullshit, just bullion. Pieces are imprinted with their respective periodic table element symbol, atomic number, and mass.
Titanium slabs come in a choice of 5-ounce cubes or full 1-pound pucks. Copper versions come in 10-ounce cubes or 1-pound bars.
