Purchased in the summer of 2024. Hardly used. Includes a cold pack. Please note that this is not a new item. Overview of Tanpei Pharmaceutical Kangaroo Cooling/Heating Soft Sheet for Baby Carriers, Absorbent and Quick-Drying, Circus Design Peace of mind for long outings! The special gel melts slowly and releases moderate coolness gradually, so the coolness lasts longer. Dedicated cover with temperature adjustment sheet to maintain the optimal temperature A dedicated cover with a temperature adjustment function that gently transmits coolness without directly cooling the baby's body. It also has excellent cushioning, enhancing the baby's comfort. Soft gel that doesn't harden even when cooled Because it's a gel made specifically for cooling and heating babies, it doesn't harden even when cooled in the freezer, and it fits gently against the baby's body. Also, because it cools by contacting the body with a large surface, it provides thorough cooling. Warm it in the microwave for year-round comfort! Warm in winter By warming the gel in the microwave, it can be used as a heating sheet. It comfortably supports outings in the cold winter. Precautions for use If left in contact for a long time, the baby may become overcooled or overheated due to the humidity of the gel pack, clothing, and outside temperature, which may lead to poor health or low-temperature burns, so parents should pay close attention. For safety, never attach it in a way that interferes with the functions of strollers, car seats, or baby carriers. There is a risk of accidents due to the straps, so the attachment must be done by a parent, and with sufficient care. Make sure the child does not play with the straps and secure them firmly. Do not use this product for any purpose other than its intended use. Store out of the reach of children.
