This pouch is too specialized for rice balls.
Originally, my child (toddler) would carry a water bottle over his shoulder when going to the park, but I made this for personal reasons so that he could carry not only drinks but also food.
The front panel is transparent to show off the type of rice ball.
There is a partition pocket inside, so you can keep GPS such as air tags, house keys, etc.
It can be used alone using the included strap, but if you use the Velcro tab on the back, you can also use it with a water bottle strap.
Also, if you attach a carabiner to the webbing that is commonly found on the shoulders of backpacks, you can mount it on both shoulders, making it ideal for carrying food while you are on the move.
You can also use it as a "bandalia" style by connecting a carabiner etc. through the two tape loops on the top and bottom and wrapping it around your body. (*Imagine Chewbacca.)
*The piss name on the shoulder pad in the image has been removed due to a change in specifications.
