Brighten up your housekeys and gym bags with the Patented BEAM LED Keychain! Great for co-branding, the Beam allows for engravable logos and messages in the clear acrylic surface, and full color printing on the black casing. The keychain features an on/off switch on the top of the plastic that controls the function of the LED. When the keychain is turned on, the LED illuminates the clear acrylic and engraved message in the color of the light.
