The secret compartment keychain is handmade from Purpleheart also known as Amaranth.The freshly cut wood is a dull grayish/purplish brown color but with exposure to the air and UV light the wood changes to a deeper eggplant purple. Purpleheart grows in Central and South America from Mexico to southern Brazil. The hardware is plated in 24kt gold.

The secret compartment keychain is also called a pill box or toothpick holder as they can be conveniently stored inside. The secret compartment can also provide a convenient and stealthy place to keep an extra bill for those "just in case" situations.
