While there are many products based on the concept of "preparation", this product succeeded in suggesting a form of preparation by replacing emergency "housing" with a familiar item. This product was highly rated as it can "naturally" replace an existing daily item: for example, it can be used in an existing cushion cover. Its functionality in use is designed and explained based on robust knowledge, and every element of this product is composed of necessities. Although the idea itself is simple, the beautiful contrast produced by the highly dense functionality and expertise makes this product more esthetic. We expect that this product will fit in our daily lives hereafter as one of the regular must-haves in emergency. This is a great item that removes a barrier between "preparation" and "living."
