The "Rakupita Structure" tightly seals and prevents leaks. Simply tighten it until the marks line up. It seals snugly and prevents leaks.
The slanted spout and handle make it easy to drink, so you can drink without tilting the mug or tilting your face up.
It can be sterilized by boiling, microwave oven, or chemical solution (strap excluded).
