In Japan, kids in Elementary school uses Red , Black and Yellow school bag. For example the girls would use Red bag and boys would use Black bag.

In Japan they are called Ransel bag or Randoseru , I presume “Ransel” is the brand name. We see this often in manga and anime where kids tugging their school bags right?

Now the paper craft we have here is made for 1/12 size which means your figma, figurine and paper craft model can use it as an accessory.

Pretty cool stuff to use as an accessory. Make sure to use a very hard paper to make it look even better.
