Missing mechanical pencils, colour pencils, glue sticks

I can say that late Sean is very clumsy, he lost of mechanical pencils, colour pencils, erasers, and glue sticks. Well I have always provide him one mechanical pencils, twelve colour pencils, one eraser, one glue stick and one pair of scissor!

I always need to purchase the stationery because he's losing them often. I have put label with his name and class room but sad to say nobody ever return them! I don't know why some classmate in his class likes to take his belongings. He fear to tell teacher because the classmate will treat him bad.

What do you do about? Some parents say nevermind they are just stationery. Some parents do mind because got classmate took home her son's colour pencil box and inform teacher only the classmate will return next day. Yeah the classmate that took other people belonging always tell, never take it back or take it. Teacher's know about the children character after months of teaching them in class.
