Ultrasonic Cleaning Pen GT-778 Rechargeable Handheld Spot Cleaner for Jewelry Glasses Watches Dentures

The Ultrasonic Cleaning Pen GT-778 is a rechargeable, handheld cleaning instrument engineered for precise, on-the-spot maintenance of delicate valuables. Instead of soaking everyday items in a bulky tank, this slim pen-shaped device channels high frequency sound waves through a stainless steel tip to lift dirt, oil, oxidation and residue directly from the surface that needs attention. For jewellery retailers, optical stores, dental clinics and gift wholesalers, the GT-778 turns routine after-sales care into a fast, repeatable and professional service that can be performed at the counter, in the workshop or at home.

Built around a 50 kHz transducer and a compact USB Type-C battery, the pen delivers continuous cavitation cleaning without cords, chemicals or complicated setup. A single charge covers dozens of cleaning sessions, and the sealed IPX7 body allows the tip to be rinsed under running water after use. Every unit is assembled from durable ABS and SUS304 stainless steel, then individually tested before packing, so importers receive a consistent product that performs the same on the first day and the hundredth.

• 50 kHz Ultrasonic Cavitation: High frequency sound waves create micro bubbles that gently dislodge dirt, grease and oxidation from jewellery, glasses and precision parts without abrasive scrubbing.
• Rechargeable USB Type-C Battery: The integrated lithium battery is charged through a standard Type-C port in about 1.5 hours, removing the need for disposable batteries and cutting long term running costs.
• IPX7 Waterproof Sealed Body: The fully sealed housing allows the cleaning tip and body to be rinsed safely, keeping the device hygienic between uses in retail and clinical environments.
• Pen-Type Handheld Design: At roughly 165 mm long and 65 g, the GT-778 reaches tight settings such as ring mountings, watch bracelets and eyeglass hinges that a traditional tank cannot access.
• One-Touch Operation with Auto Shut-Off: A single button starts cleaning and the built-in timer stops the pen automatically after 10 minutes, protecting the transducer and simplifying staff training.
• Low Noise and Low Power Draw: Operating below 60 dB while drawing only 5 W, the pen is quiet enough for a sales counter and economical enough for continuous daily use.
• OEM and ODM Ready: Logo printing, colourways, retail gift boxes and user manuals can all be customised for private label programmes and promotional campaigns.

The GT-778 is designed for businesses and users who need fast, gentle cleaning in a small footprint. Jewellery shops use it to refresh rings, earrings, chains and watch bracelets before display or before handing an item back to a customer. Optical retailers clean spectacle frames, nose pads and temple hinges at the counter. Dental labs and clinics remove residue from removable appliances, dentures and small instruments. Electronics and hobby workshops rely on the pen to clear oxidation from connectors, contacts and small precision parts.

Because the cleaning action is targeted rather than immersion based, the pen also suits antique dealers, model makers and collectors who cannot risk soaking fragile items. It is equally effective as a household tool for glasses, razors and small metal accessories, which makes it an attractive gift item and a strong add-on product for retailers and online sellers.

Each GT-778 is packed in a printed colour gift box with a moulded foam insert, a Type-C charging cable and a bilingual user manual, then protected by an export grade corrugated carton. Bulk orders can be supplied with customised artwork, private label branding and market specific plug or cable options. All units are function tested, frequency checked and aged before shipment, and the product carries a one year warranty covering manufacturing defects. Standard lead time is 15 to 25 days after deposit, with sample orders available for evaluation. Please contact us to request a quotation, confirm MOQ and discuss OEM cooperation.
