【Usage Precautions】
・In low-temperature environments, moisture within BOVEDA may freeze or harden. If this occurs, warming it in your palm will restore it to its normal gel state. Even if the state changes, the product retains its original efficacy as long as it returns to a gel-like consistency.
・Do not use with other humidity control agents. They may interfere with each other and prevent normal effectiveness.
・While the pack is sufficiently sturdy, we recommend using it inside the included pouch in case of damage.
・The internal liquid contains salt. If the pack breaks and the liquid comes into contact with skin, rinse thoroughly with plenty of water.
