The secret compartment keychain is handmade from Shagbark Hickory. The heartwood tends to be light to medium brown with a reddish hue; the sapwood is a paler yellowish brown. Hickory is among the strongest and hardest woods native to the United States and grows in the eastern United States. The hardware is plated in chrome.
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.
