RossRefreezing instant cold packs can damage the chemicals inside and affect their ability to provide cooling when needed. The components in the pack may not refreeze evenly or may not reach the required temperature for effective cooling after being frozen a second time. It is best to follow the manufacturer's instructions and avoid refreezing instant cold packs for optimal performance.
