Wireless Charging Straight Hair Comb with USB Power, Negative Ion Heating, Tourmaline Ceramic Heat Conductor 21mm-30mm, 10 Temperature Settings, 3D Gradient Pink or Green, Dry Hair Styling Tool
USB Wireless Straight Hair Comb with Tourmaline Ceramic Heat and 10 Settings

This USB-powered straight hair comb is designed for dry hair styling without a mains cable. It uses a tourmaline ceramic heat conductor with a 21mm-30mm diameter and offers ten temperature control segments. The negative ion heating function is part of the comb's stated operation. The shell has a spray-painted 3D gradient finish, available in pink or green, with further colour names listed as Pink, Pink and purple, and Purple. Power is supplied through USB, so a compatible USB source is needed and is not included. The pack contains one electric comb. No exact temperature values, charging time, battery capacity, automatic shut-off, cable, adapter, or storage pouch are stated in the source information. This compact format suits dry hair straightening where a cordless, USB-connected tool is preferred.
Features and Construction

The comb combines a USB power supply, a tourmaline ceramic heat conductor, and ten temperature control segments. Its 21mm-30mm heat conductor diameter gives a defined heated surface for section-by-section straightening. The body has a spray-painted shell in a 3D gradient finish. These details are supported by the source information and keep the product focused on dry hair styling.
Material and Build
The heat conductor is made from tourmaline ceramic, which forms the contact surface for straightening dry hair. The shell uses a spray paint process to create the 3D gradient appearance. The stated colours are 3D gradient pink and 3D gradient green, with additional colour names listed as Pink, Pink and purple, and Purple. No other construction materials are given in the source text, and no performance claims about the coating or ceramic are made here. The build details are limited to those stated facts, so the description does not extend beyond them.
Size and Practical Fit
The heat conductor diameter is 21mm-30mm, which is the only measurement provided. This size is relevant for styling dry hair in sections, and it gives a clear indication of the heated surface area. Because the comb is USB-powered, it can be used away from a mains socket when a compatible USB source is available. No length, weight, or cable measurement is stated, so those dimensions cannot be confirmed. The compact nature of a comb format may suit travel or small storage spaces, but no travel case or pouch is included according to the packing list.
Uses and Placement

This straight hair comb is intended for dry hair and uses a USB power supply. It can be used for personal styling at home or in other locations where a USB power source is available. The ten temperature segments allow adjustment, and the negative ion heating function is stated as part of the product. The 3D gradient finish gives a distinct look in pink or green.
Event or Professional Use
The comb may be used for dry hair styling before events or during professional touch-ups, provided a compatible USB power source is accessible. The 21mm-30mm heat conductor diameter supports working in sections, and the ten temperature control segments allow the user to select a setting. The 3D gradient colours, including pink and green, give a recognisable appearance. No professional certifications or salon-specific claims are made in the source information, so the comb is described only for its stated dry hair straightening function.
Everyday Home Use
For everyday home use, the USB power supply mode means the comb can be connected to a suitable USB port or adapter when needed. It is intended for dry hair, so it is best used on hair that is already dry. The ten temperature segments provide adjustment, and the tourmaline ceramic heat conductor forms the heated surface. The spray-painted 3D gradient shell is available in pink or green. No automatic shut-off, charging time, or battery capacity is stated, so users should follow their own safe USB power practices.
Benefits and Buying Value

The main practical value comes from the USB power supply, the tourmaline ceramic heat conductor, and the ten temperature control segments. The comb is designed for dry hair straightening and is available in 3D gradient pink or green. The pack includes one electric comb. No price, savings, or comparison figures are provided, so value is described only through the stated features and the reusable nature of the tool.
Reuse and Low Maintenance
The comb is a reusable styling tool rather than a disposable item. Its spray-painted shell and tourmaline ceramic heat conductor can be wiped clean once cool, using only minimal low-risk care tied to the stated materials. No specialist cleaning solutions or care instructions are provided in the source text, so no specific maintenance routine is claimed. The USB power supply mode means no mains cable is required during use, provided a compatible USB source is available. The packing list includes one electric comb only.
Why Choose This Product
This comb may suit buyers who want a USB-powered straight hair tool for dry hair with a tourmaline ceramic heat conductor and ten temperature settings. The 21mm-30mm heat conductor diameter is the only stated measurement, and the 3D gradient colours include pink and green. The negative ion heating function is part of the stated operation. No exact temperature values, battery details, charging time, or automatic shut-off are given, so the choice rests on the supported features: USB power, ten adjustment segments, tourmaline ceramic, and the 3D gradient finish.
