To be released on Feb. 21, 2025

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 MTR-W075/W088 on Friday, February 21, 2025.
In September 2024, we released the “Vacuum Insulated Bottles MKR-W035/W050/W060,” Tiger’s first one-push mug-type vacuum insulated bottles with Raku Raku Cap, a stopper that forms part of the gasket. The product was highly evaluated for its ease of cleaning, ease of use with one hand, and superior temperature retention, and was awarded Best Buy in the December 2024 issue of “MONOQLO by 360Life (SHINYUSHA).”*
The new “Vacuum Insulated Bottles MTR-W075/W088” are available in two sizes, 0.75 L and 0.88 L, for those who “don’t need 1 L, but 0.6 L is not enough…” They are the perfect size for a long period of work that requires concentration, your child’s club activities, or family holiday outings.
As with the “Vacuum Insulated Bottle MKR-W Series,” the ease of cleaning and ease of use are made possible with a one-push mug with Raku Raku cap, a stopper that forms part of the gasket. The product is dishwasher/dish dryer–safe, so you can clean it easily every day.
We will continue to refine our proprietary technology cultivated over our 100-year history in the 101st year and beyond 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.
*Awarded for MKR-W060

Stopper that forms part of the gasket”Easy-to-clean cap”
The bottle is provided with Raku Raku Cap, the stopper that forms part of the gasket. The one-piece stopper saves you from having to attach and remove a gasket, eliminating worry about forgetting to attach it to the stopper, attaching it incorrectly, or losing it. The removable spout is easy to wash, keeping it sanitary.

Dishwasher/dish drier safe
The stopper, spout, and main body are all dishwasher/dish drier safe.
*Detach the stopper and spout from the main body before putting them in a dishwasher.
*The bottle may not fit in dishwashers and dish dryers depending on their sizes.

Super Clean Plus prevents stains and odors and is resistant to rust
The smooth and lustrous Super Clean Plus is applied to the inner surface of the bottle. The surface prevents stains and odors and is resistant to rusting, allowing you to put a sports drink containing salt in the bottle.
*Care for the bottle by rinsing with water immediately after use.

Magically light!
The perfect Mujuryoku bottle to carry around
By making the wall of the bottle’s inner tube thin using Tiger’s proprietary spinning technique, we have made the product lighter.
The 0.75 L size weighs approximately 310g, making it easy to carry.
