Disaster prevention whistle Shizune/Tosho Rubber Industry

Bendable and unbreakable disaster prevention whistle that makes a sound even when blown lightly

The material is silicone rubber, which is widely used in medical fields and cooking utensils. Small and lightweight, this is a disaster prevention item that should be worn at all times.

Because it is rubber, it can be bent back to its original shape and is water-resistant.

It will not be damaged by shocks during emergencies such as confusion or accidents during disasters, making it impossible to produce sound when the time comes. *No sound will be made when the item is bent

Sound is produced even with small breaths.

Even children and the elderly with limited lung capacity can produce sound, even if they are in a state of reduced physical fitness. The molds were made over and over again so that the sound could be produced even with small breaths.

*Noise measurements taken with 24 prototypes with the cooperation of the Sumida Ward Office showed an average sound level of 70 to 80db (average noise measurement over 5 seconds).

Small and lightweight portability that blends in with everyday life

The whistle itself is small and lightweight, weighing only about 3g. The important thing is to always have it on your person in case of an "emergency. With a wide variety of colors and a simple yet cute form, we pursued a design that you won't mind wearing it on a daily basis.
