Get creative with your scientific side by choosing TWO elements such as O Mg or Y Es for a custom engraved acrylic keychain made just for you!

A thick keychain will last longer than a thinner one. Your double element keychain will be engraved on extra thick transparent acrylic.

The keychain is finished with a strong stainless steel key ring. Element: Choose your favorite 2 elements! These should be real elements listed in the current periodic table. Please list the elements in the order you wish them to appear. Size: 3 1/8" This is the full length of the keychain including the key ring.
