The Sigg Travel Girl Shanghai 0.4 L is a colorful drinking bottle in which your child can take a drink to school without any problems. The drinking bottle has a screw cap that is leak free, so the chance that your child's school bag gets wet is very small. The aluminum material is lightweight and sturdy, so the bottle will not break easily when it falls to the floor. The inside of the bottle is tasteless, so drinking from this bottle does not taste like metal. The bottle is free of harmful chemicals.
