A cute eco stick featuring Chiikawa, Hachiware, and Usagi lined up has appeared. A convenient item that can be filled with ice water or hot water and used as an ice pack during hot seasons and as a hand warmer or hot water bottle during cold seasons. Its slim design makes it easy to carry, so it will be useful regardless of the season. Let’s get through both hot and cold weather together with Chiikawa and friends.


Hello! I’m Sekai, a virtual reporter for Perfect World Tokyo.
Since this eco stick is washable and reusable, it’s environmentally friendly. It’s great that you can take measures against heat and cold while enjoying the cuteness of Chiikawa, which naturally leads to being eco-conscious.

An eco stick with a fresh light blue color and a design featuring Chiikawa, Hachiware, and Usagi lined up.

The Chiikawa characters holding hands and lined up are absolutely adorable.

Just looking at it makes you want to smile.

When you fill the case with ice water or hot water below 80°C, it can be used as an ice pack or hand warmer.

The size is 17.5cm × 5.8cm × 5.8cm. Its slim and compact design means it won’t take up much space in your bag.

Furthermore, the case has a ring attached, making it convenient to carry.

During hot seasons, use it as an ice pack—apply it to your neck during sports, leisure activities, and outdoor events for cooling down, or use it for fever relief and heat stroke prevention. During cold seasons, it can be used as a hand warmer or hot water bottle, so it will be useful year-round.

The fact that it’s washable and reusable is also a plus. Why not incorporate this fun and eco-friendly item with Chiikawa and friends?

A stainless steel bottle is also available in the same design.

A direct-drink type that opens and closes easily with one touch. This one has a capacity of 600ml.

A cold-insulating bottle with a lock function that’s easy for children to use.

Also available in a larger size with a capacity of 800ml.

The back also features a flower pattern, making the design cute even from behind.

Children will be delighted with it too.
