Jansen Slimming Bag is a slimming product, and its switch green is one of the common colors, but whether it is high-grade or not can not be judged simply by color. The quality and performance of the product mainly depend on its material, technology and science. Therefore, it is impossible to accurately judge the grade of Jansen's thin bag simply from the color of the switch. I suggest you make a comprehensive evaluation from the aspects of brand reputation, user evaluation, product certificate and composition. So as to choose the slimming products that suit you.
