Drinking Cup 290ml Colorful Eco-friendly Drinking Cup 6 Pcs Acrylic Dots Plastic High quality and non-toxic Before getting into the design of the cup, we are very concerned about the safety of the material. Therefore, PV is used, a non-toxic, odorless and high temperature resistant material, which is mainly used to make milk bottles. Its temperature range is between -20 C and 120 C. . Thickening design The thickening of the floor can not only play the role of drop protection, but also increase the thickness of similar glass, and the appearance is beautiful and atmospheric. Holding it in your hand also creates a special feeling of meditation and peace. . Concave-convex anti-slip Our tumbler has a concave-convex anti-slip design which greatly increases the friction between the hand and the cup. Whether it's an adult or a child, it can be used with confidence. . Unbreakable The clear advantage of the cup made of PV material compared to glass is that it is not easy to break. Your baby's delicate hands will not be scratched by sharp glass shards, and it is not as hot as a glass, which makes it suitable for many consumer groups. .
