Customer Testimonials

“For an outdoor event where weather and temperature were unpredictable, and without any nearby facilities for receiving refrigerated goods, we utilized the COLD STORAGE BOX Portable. We delivered and set it up the day before the event to store received goods. During the event, it was used for various purposes and greatly contributed to food safety management.”
Company A, Event Management Company
“The limited refrigerator capacity of our food truck made the additional storage provided by this product very convenient. Previously, we had to deliver items via courier daily, but being able to transport and store everything at once reduced both the time and cost associated with shipping and receiving. The cooling capability was more than adequate even in summer outdoor conditions, ensuring stable temperature control for ingredients. It also allowed us to pre-chill drinks, which ensured we could serve cold beverages on the day of the event.”
