A new vacuum-insulated bottle with an upgraded stainless steel straw meets high-capacity needs.

Tiger Corporation (President: Yoshisato Kikuchi, Headquarters: Kadoma City, Osaka) (“Tiger” or “we”), a world leader in thermal control technology, will release the Vacuum Insulated Bottles MTS-W075/W088 (for cold drinks only) on Saturday, February 21, 2026.

We launched MCS-A050 (500 mL), the first Vacuum Insulated Bottles with a stainless-steel straw, in September 2022.

MCS-A050 has been well received by many customers, with customer surveys showing that “It comes in handy while working because I can drink with one hand without lowering my eye level” and “I like that the stainless-steel straw is hygienic.”

On the other hand, there were many requests for larger capacity, such as “500 mL is not enough for the hot summer months” and “I want a larger capacity.”

In response to these needs, we will launch the new “Vacuum Insulated Bottle (for cold drinks only) MTS-W Series” as a large-capacity model. The MTS-W series has increased capacity while maintaining the reliability and ease of use that only a stainless-steel straw can provide. It can now be used fully in a wide range of situations, from everyday use to sports.

The bottle is equipped with a stopper with an integrated gasket. This greatly reduces the time and effort required for daily cleaning.

We will continue to refine our proprietary technology cultivated in our history of over 100 years to provide high-quality products to the world so that our customers’ daily lives will be further enriched by Tiger Corporation’s Vacuum Insulated Bottles.
