The vacuum insulated bottles of the “Colobockle” series with characters on the holder were created in collaboration with “Colobockle,” a humorous worldview created by picture book artist Michiko Tachimoto that mixes the everyday with fantasy. Launched in 2006, the series has been well received by both children and adults for a long time.
The new MBR-G06G will feature designs by Michiko Tachimoto depicting unique animal illustrations with a distinctive touch of Colobockle.
The back of each holder displays a cute animal butt pattern as well.
Lion “RL”:
A signature animal on a Colobockle bottle.
Continuing as the symbol of the series, the new design features a cheerful and bright character.
Alpaca “PA”:
Alpaca was chosen as a fluffy and soothing animal.
It is a soothing and gentle design.
Cat “YN”:
The unique design depicts a cat, a classic popular animal,
with a touch that is unique to Colobockle.

(2) Two-way bottle with direct-drink spout and cup units
By replacing the stopper (lid) unit, you can use the direct-drink spout (direct drinking) or the cup unit, depending on your needs.
*The direct-drink spout is designed for drinking cold beverages only
You can choose the way of drinking between direct drinking (easy for small children) or drinking from a cup as your child grows.

(3) Machine-washable carrying holder
Made of impact-resistant, tear-resistant material. It not only protects the bottle from shocks, but is machine-washable if it gets dirty.
We shaped the bottom using a three-dimensional shaping (molding) technique to increase its stability and durability.
Other Features
Hygienic Super Clean finishing to resist stains and odors
The smooth and lustrous Super Clean finish is applied to the inner surface of the bottle.
It resists stains and odors so that the interior of the bottle can always be kept clean with a quick wash. You can also put a sports drink in the bottle.
(Clean the bottle immediately after use.)
Entirely washable bottle body and stopper
The bottle body and stopper (cover) can be washed in its entirety for hygiene.
