【High Quality & Large Capacity】 The main body is made of high-quality ABS material, which is environmentally friendly, stable, and corrosion-resistant. The ultrasonic cleaner has a 300ml water tank. It can be used for various items such as glasses, precious metals, metal watch bands, electric shaver blades, and fountain pen nibs. For stubborn dirt, it is recommended to add 1-2 drops of neutral detergent. 【Optimal Vibration Frequency & 360° All-Around Cleaning】 Based on research and development experience, it has been found that a vibration frequency of 52,000Hz is the most effective for cleaning and does not damage objects. The ultrasonic cleaner generates bubbles in the cleaning tank filled with liquid through 52,000 high-speed vibrations per second. The ultrasonic vibrations create countless invisible fine bubbles (cavitation) in the water. The shock waves produced when these bubbles (cavitation) burst pulverize the dirt in the tiny crevices that are out of reach. 【3-Stage Adjustment & Timer Setting】 The digital ultrasonic cleaner is controlled by an industrial-grade microcontroller chip, with an automatic one-button cleaning design, making operation very easy. It is equipped with a 2-stage timer and 3-mode function, with 5-minute cleaning/washing and 10-minute cleaning/UV cleaning options, allowing you to set the cleaning time according to the degree of dirt and the usage scenario. Switching between buttons is easy and quick without complicated operations. By opening the cover, you can observe the clean state of the object at any time. It is very convenient for cleaning. 【USB Rechargeable】 USB rechargeable and cordless. A fully charged large-capacity battery can be used for about 1 hour. The ultrasonic cleaner adopts rubber feet to prevent slipping and reduce the vibration of the machine, improving stability. The ultrasonic cleaner weighs about 320g, making it convenient to carry when traveling or on business trips. 【Precautions】 It is strictly forbidden to turn on the power without water. It is strictly forbidden to add corrosive detergents. It may not be possible to completely clean dental plaque, yellow stains, black stains, and nicotine stains on dentures. ☑︎ Brand new, unused item ☑︎ Unused items have not been tested for operation ☑︎ Immediate purchase is welcome, no need to ask for permission ☑︎ Only one left, first come, first served ⬇️ Other products are here #memeるかりshop s942 $$2999
