UJack Shuriken Ice Packs for Vacuum Hybrid Containers (Square Shuriken)

This ice pack fits perfectly into commercially available cylindrical containers, leaving absolutely no dead space. The secret is its unique shape, which allows the four compartments to neatly accommodate the caps of plastic bottles. This maximizes the space inside the container, allowing for more efficient cooling. Our ice packs utilize the natural flow of cold air to provide excellent cooling efficiency. Once cooled, the effect lasts for 8 to 12 hours. Using two packs together further enhances the cooling effect. Safety is also a consideration. The ice pack contents are made of high-performance PCM (Phase Change Material). The container is made of non-toxic high-density polyethylene (HDPE), which can be stored with food. This HDPE container is extremely durable and can be reused multiple times. These features allow the Shuriken ice pack to provide a streamlined and perfect cooling experience that matches its shape.
