This glowing keyring makes an excellent promotional gift, since it'll make your logo shine! It's also a perfect gift for a concert- or club-goer who might need a little extra light at dark venues. It slowly fades through 7 different colors, and batteries are included. This keyring and keychain would also make a touching realtor gift to a new homeowner or give a festive touch to a hotel room key. You can have your logo or text engraved with perfect clarity and detail!
