A classmate stole a box of straight pen in the stationery store. Will the boss find anything missing?

It is only a matter of time before the boss will find out about this situation. Because your classmate stole a box of pens, the quantity is still relatively large, and the boss will find it when he checks at the end of the month. But because the amount is not large, it is estimated that the boss will not call the police. But now there are surveillance everywhere, and once you enter the store, every move will be recorded. I hope your classmates don't play the trick of hiding their ears, or they will hurt themselves in the end!
