Let us introduce Matsuda Paper Industry.
They sell desks and chests for children, which are all made of cardboard.
They’re very light but some of them are really strong. For example, the chairs can hold up to 70kg.
Also their cardboard items are easy to build because they don’t require any tool or glue.
They sell toys too.
They have an online shopping website so check out their products there.
