May I wash the pencil bag? What if the pencil case is black and dirty?

You can smell it when you buy a pencil case. All kinds of toxic and harmful organic compounds have a certain smell. Products with excessive pungent smell should be purchased with caution.

3, use knowledge: the zipper protection of the pencil case is the most important, but the pencil case is unbalanced, so it is rarely done once, it takes 2-3 times, so don't pursue fast, slow and safe when pulling the zipper.

4. All stationery put into the pencil box must be covered, the knife must be far away, and nothing should be exposed. The pen must be covered and the pencil sharpener must be covered.

Don't press the pencil box, otherwise the stationery and schoolbag will be damaged together.

6. Do not use the zipper as a portable part.
