Future school bag

Do you want to know what the future school bag looks like? Ah! Ah! Let me tell you, this kind of bag is what I invented, very practical. As for how to use it, please listen to me slowly.

First: He has a walking function. If you have a lot of books in your bag every day, the back is very heavy and heavy. When you put the yellow button on the bag, he will grow his hands and feet and hold you.

Second: He can prevent others from taking your stationery. If you go out to play every time, there are many students who love to take other stationery. If you take your stationery, they will steal it after they have stolen it. The things they took away were sent back.

Third: He will organize his schoolbags. If one day, after you have finished breakfast, you are already late. You just need to put a messy book into your schoolbag. Just press the blue button, because the schoolbag will automatically You sort out the bag.

Hey, in fact, the introduction just said "to tease you", it may be my invention in the future, now I can only say two words - far away.
