(*1) Antimicrobial property
The proportion of bacteria on the surface of the product is 1/100 or less of that on the surface of a non-treated product, and the antimicrobial effect remains after durability tests. Antimicrobial properties are determined from the results of tests conducted in accordance with the ISO 22196 international standard.

Vacuum insulation technology

Tiger's vacuum insulation technology keeps drinks colder for hours. The copper foil in between the two stainless-steel walls supports temperature retention. Cold drinks will not cause condensation on the outside of the bottle and hot drinks will not cause the bottle to become too hot to handle.

Proprietary “Super Clean Plus” technology

The inside of Tiger’s bottles has smooth and polished surface that is tough against stains and rust.
