Playful Pencil / Pencil

Playful Pencil
Playful Pencil

As we know, a pencil will be shorter and shorter as it is used. Around one-third of a pencil will be thrown away; that is, one-third of the resource is wasted. But few people care about this, especially the kids. They love things that are new and interesting.
Playful Pencil makes itself playful to let people save resources. Each pencil has an internal thread and an external thread on the two sides, so that they can be connected one by one. If a pencil is too short, just add a new one to its tail and it will become a new long pencil! Of course, you can add as many colorful pencils as you like. Maybe you will worry that it's too long to use!
