Blow the whistle on a promotional item for a safe and fun freebie! The Oscen LED Whistle Keychain lights up thanks to the push-button LED light that will help them find key holes, door handles or any other small area once it gets dark. These promotions come in multiple colors and have a silver split ring to slide right onto their existing keychains and include a screen-printed trademark or logo on one side for keeping your brand on their minds. Women’s and children’s groups will appreciate the whistles, which can be used for safety purposes or just a great way to get someone’s attention. Make a little noise with this marketing item!
