If you change the ingredients inside, may this be all right for lunch every day? I found a case where you can easily make and carry a lot of "bomb rice balls", so I tried using them.
This product is named "Bomb rice ball case that can be made without squeezing". If you use the attached "push mold", you can make rice balls without squeezing, and you can carry it in the case as it is. The capacity of the case is 290 ml. It's about twice the size of a standard convenience store rice ball.
Let's use it now.
Although it is a product that is not particularly novel, it is a little touching when you actually use it. You can make it so easy and beautiful. However, it may be a little difficult to wrap it in seaweed because it can be made much larger.
It is available on various EC sites, and the price is around 400 yen. There are also models designed with popular characters, so if you are interested, please check it out.
