This is a great value refill. Please be sure to refill into an AYAKA Brightening Amulet Milk container. 1. Thoroughly wash the AYAKA Brightening Amulet Milk (100mL) container and the inside of the pump and cap with warm water (avoid boiling water) and dry thoroughly. 2. Cut off the tip of the spout along the dotted line. (Please note that holding the pouch too tightly may cause the contents to spill out.) 3. Insert the spout into the mouth of the container and slowly pour the contents in. 4. After refilling, record the manufacturing code on the bottom or cut it off and keep it. This may be required when making inquiries about the product. Please be careful if you have a history of allergies to the ingredients. *The active ingredient, L-ascorbic acid 2-glucoside, may cause the color of the contents to change, but this does not affect the quality. <Caution> - Never wash the container, pump, or cap with boiling water as this will cause deformation. Residual moisture may cause the contents to deteriorate, so be sure to dry thoroughly after washing. Also, drying it with a hair dryer or similar may cause it to deform. After opening, refill the entire container at once. When opening or refilling, be careful not to cut your hands on the spout or the edge of the bag. Do not store in direct sunlight or in places with high or low temperatures. If the contents are difficult to dispense after refilling, press the pump several times. If the pump becomes dirty or does not work properly, purchase a new unit. Use with care, paying close attention to any abnormalities on your skin. If it does not suit your skin, discontinue use. Not a food or drink
