1. The high impedance tip is made of metal material, it is high resistance and high temperature resistant.2. At high temperatures, there is no bending, no softening, no oxidation, less carbon and so on.3. 9 different tips are used for different functions, such as for large-scale rendering, fine rendering, and drawing even lines.4. Can be used with 30-50W pyrography machine.5. The strength within 600 degrees is not bent without heating and the bending resistance of the writing head made by electric heating wire is much better than 800 degrees.Power: 30-50WUse voltage: 3-5V.Temperature: 0-1000Celsius (normal use temperature)Applicable models: LH30, LH40, LH50, LH60, LH70LH80, LH90, LH100.Colour:SilverMaterial:metalSize:3.5 x 1 x 0.2cmPackage Contents:9 x pyrography wire tipsOnly the above package content, other products are not included.Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
