This item is priced at USD 0.50 each (tiered quantity applies — for example, a $48 fee corresponds to selecting 96 pcs). Designated for additional shipping and customization adjustments. When you place an order on Yunyisonic.com for an ultrasonic cleaner and require special model customization—such as specific frequency, power rating, tank size, extra features, or wooden-case packaging and express shipping—this “Upgrade Service Fee” product allows you to formalize the additional cost. It is not a separate machine, but a service adjustment to your main order.
