Strap not included. This is an original whistle made by Traveler's Factory, made of solid brass. It produces a high-pitched sound when you blow into it. If you carry it around with you at all times, such as attaching it to a key ring, the zipper pull of your bag, or attaching it as a charm to the rubber band of your Traveler's Notebook, it may come in handy someday. The more you use it, the more the color of the brass will change, giving it a tasteful antique look. Size: Whistle diameter 8mm Height 35mm Shipping Handling time is based on our shipping policy.
