It can be used as a rice ball wrap or a container! I found a product called "Easy Rice Ball Pack" at Daiso, so I bought it.
"Easy rice ball pack" is a container that is useful for making and carrying rice balls. Made of soft silicone, you can carry it as it is after stuffing it with rice and squeezing it. You can wash and use it as many times as you like without throwing it away like a wrap. There were two sizes, "Large", which can make about 120g (4.23oz) of rice balls, and "Small", which can make about 80g (2.82oz) of rice balls.
Let's try it now.
You can easily make beautiful rice balls, but there are some points to note. When you take out the rice ball, the edge of the pack may get caught and collapse, so it is safer to hold it firmly. Also, since the color is easily transferred to the silicone material, it is better not to use it for rice containing ketchup or curry powder.
Although it has some weaknesses, it is also compatible with refrigeration / freezing and microwave ovens, and is a "simple rice ball pack" that seems to be useful. If you want to hold the rice balls in a beautiful triangle and avoid throwing away the wrap, try it. The price is, of course, 108 yen (tax included) per piece.
