Thermoplastics. I've worn both. Just try the counter in the mall. The coat feels different. It hurts a little to wear under the high-profile function. But thermoplastics are different. It's comfortable to wear casually It's still hot It is very helpful for slimming the back and waist and abdomen. You made the right choice/the good effect is the last word. Ha ha. My perfume shop/. Taobao shop. I am an old customer of her family.
