SGS Certification: The safety cabinet is made of healthy and environmentally friendly ABS material, 100% non-toxic and odorless, allowing your baby and children to live a healthier and safer life.< /p> Rotating buckle design: this design is very easy to use, you just need to flip and click easily. Pressing buckle design: very easy to use and use for adults, but complex enough that kids and pets can’t do it all. Ultrasonic Bonding Technology: All parts of the item are fused together by ultrasonic welding. Further down, the two small pieces at the top of the item will never fall off. Don’t worry if your child puts the little button in their mouth. Strong adhesive: The adhesive is very strong, as the 3M tape was not strong enough for us, so we researched and found a stronger adhesive that would save our kids from struggling. (You can deduce it by heating (a hair dryer) for a minute or two and it comes out easily.)
