LotFancy offers a set of two reusable hot and cold packs designed for effective first aid treatment of various injuries. Each gel pack measures 10.5 by 5 inches and is filled with non-toxic silica gel, ensuring safety during use. These packs maintain flexibility even when frozen, making them easy to apply to different body parts. Users can heat the packs in the microwave to relax muscles and enhance blood flow, or chill them in the freezer to help reduce swelling and inflammation.

These versatile gel packs are perfect for treating pain in areas such as wisdom teeth, back, shoulders, neck, head, face, feet, hands, and arms. For cold therapy, it is recommended to freeze the gel pack for at least two hours before application, providing a safe and effective way to diminish swelling and alleviate pain. Heat therapy is suitable for use 48 hours after an injury; simply warm the packs in hot water or microwave for 20 to 40 seconds, always checking the temperature before applying. With their ease of use and effectiveness, these hot and cold packs provide a reliable solution for pain relief and promote faster healing.
