【Sizes】Small: Approx. 15cm, Large: Approx. 21cm 【Ice Pack for Cooling】Prevents loss of cooling effect, allowing for long-term icing. Of course, the more ice you have, the longer the cooling time, but the possibility of condensation also increases relatively. 【Ice Pack for Warming】Can also be used as a hot pack with hot water below 55°C. Suitable for cold winters. 【Leak-Proof & Moisture-Proof】High-quality polyurethane coating on the back of the ice pack, and the cap is tightly sealed, preventing water leakage. In addition, the surface is moisture-proof, making it less likely to produce condensation and water droplets, allowing for enjoyable use. *Condensation may occur on the surface of the bag due to a significant temperature difference between the room temperature and the bag. Please wipe with a towel, etc., before use. ★Adding a little salt to the ice pack can slightly extend the cooling time. ❗️Caution❗️Do not heat in a microwave. Do not put water over 60°C.
