[1000g 0.38mm]

Common sense: the diameter specified in the specifications of the enameled wire refers to the diameter of the bare copper wire, apart from the thickness of the paint insulator.
The diameter of the enameled wire measured with a gauge is the outer diameter, including the thickness of the paint insulation, and the measured size is usually larger than the size of the specification standard.
The product in this link is a copper wire, Excluding coils. There are different colors and sizes of coils.
Please know that the copper wires of 1.3mm and above specifications are relatively thick and cannot be straightened after being wound, therefore, the copper wire is not equipped with a coil.
The thickened tree is not easy to damage. The shaft holes at both ends are the same size, and are more convenient to use. When the thin copper wire is wound, the coil should be placed upright to allow the copper wire to fall naturally and then wound. Please notice

Note: The diameter of the enameled wire specification refers to the diameter of the bare copper wire, not including the thickness of the lacquer. The diameter of the enameled wire we measured with a caliper is the outer diameter (including the thickness of the paint), and the paint on the wire needs to be scraped off by soldering.
