Tips for buyers: Please pay attention to the identification of materials, we use environmentally friendly latex, not those who use sugar glue, our products you can use with confidence, the difference between latex and sugar glue: latex is soft, pinch with your hands It can be easily pinched. The gum is relatively stiff and requires a lot of effort to pinch a little bit. The products are all made of latex, so you may get a little latex taste when you receive it, but it doesn't matter. Our raw materials are tested and environmentally safe. If you feel the smell is bad, please put it in a well-ventilated place. There is no smell in a day or two: the product is opened with a plaster mold, so there may be some small particles on the surface, which is a normal phenomenon.
