Instant Heat Bag comfort is the new instant water bottle, reusable with an extra-comfort cover.
It does not require hot water; the bag is heated when the disc inside of it is activated, preventing scalding.
It is practical and can be brought anywhere because it does not require water for heating.
It is ready instantly; when the disc inside is activated, heat is immediately released.
It is reusable and after use it should be immersed in boiling water to dissolve the gel and, once cooled, it will be ready for reuse.
