What's the difference between an empty drum and an ethereal drum? Which is better?
1. The color roller is made of copper, while the transparent roller is made of titanium steel. 2. The colored drum can hardly hear the echo of metal, while the ethereal drum has a strong sense of metal and a slightly poor sound quality. 3. The physical stores in big cities are basically empty. There is a lot of training, and you can meet some like-minded friends. 4. Color empty drum paint is better, 1 year replacement, 3-year warranty.
