Automatic soap dispenser: The soap dispenser does not require direct contact. The soap dispenser sensor detects your hands and automatically dispenses hand sanitizer foam. An automatic soap dispenser can help solve your hand washing problems. A super easy to use automatic foaming soap dispenser that will have your family falling in love with hand washing. Electric Soap Dispenser: Most hand sanitizers and water are mixed in one ratio 1:4, with 220ml capacity, without frequent replacement, saving hand sanitizer. You only need three AA batteries. (not include) Easy to use: just put the solution in the jar, add the battery release button. Green light on, red light off, extremely simple. Foam release: No touch required, the infrared sensor of the soap dispenser only detects the hand and releases the foam in 2 seconds. If the foam is weak, a recapture is recommended. HOLIDAY GIFT: The 8.5 x 19 cm volume is easier to store, and the cute look can be used as a home decoration. The cute appearance of the little yellow duck will attract more people. Bring 15 effervescent tablets (available for about one year): The effervescent tablet is diluted with water to form a hand sanitizer. It is recommended that the ratio of effervescent tablet to water be 1:200. (Equivalent to 1 effervescent tablet in approximately 200ml of water, with or without agitation, to speed up melting.)
