Leg patch with soothing warm steam of about 40°C. Apply the product and enjoy a gentle steam bath. Plenty of steam embraces the legs, and gently eases tension. Steam of about 40°C lasts for around 30 minutes. Thin sheet fits softly and does not peel off easily. Warms up immediately upon opening the pouch, and is convenient to use any time and anywhere! Recommended for applying on calves after sitting for a long time at work, or after traveling.
