Avogadro's Number Bracelet

Avogadro's constant: "the number of elementary entities per mole of substance". It's a big number...which is to say, there's a lot of stuff in the universe. Wear a piece of it with this hand-stamped bracelet. Available in aluminum or brass, it is sturdy enough to last for years and years. (Note that hand-stamped lettering varies a little, so yours will be charmingly unique.)

Perfect for:

• Chemists of all types
• Molecular biologists
• Science teachers
• Mole Day celebrators
• Anyone who appreciates both the extraordinarily vast and exquisitely infinitesimal nature of the universe
