This is a Fortnite learning notebook. I found it while tidying up my child's room. It has the squares of a learning notebook, so I think it can be used normally. Please, adults are welcome to use it too. It seems to be not for sale. Actually, I found a lot of new notebooks and stationery, doesn't it make you sad?! Oh, sorry. If you'd like to use it, I'll ship it immediately, so please feel free to purchase it.
