All Caldera reusable Therapy Gel is Made in the USA and can be applied either hot or cold. Therapy Gel is latex-free, non-toxic, microwave, and freezer safe and remains pliable when frozen. When used for cold therapy, put the gel pack in the freezer for at least 8 hours so that it can provide fast relief for acute soft tissue injuries and other conditions that require cold pack applications to reduce inflammation and swelling. For hot therapy, place the gel pack in the microwave for 10-30 seconds or according to the ideal temperature you like and apply on the affected area for 20-30 minutes.
The Instant Cold Pain Relief Pack is a single-use disposable product. These nifty little packs don’t need to be placed in the freezer; you just need to activate the cooling agent by squeezing the instant cold pack. Just make sure to shake well to achieve the best results!
