Joyful Color Reusable Colored Pens

Baby, Kids' and Children's Products Design Joyful Color Reusable Colored Pens by Lu Yi Joyful Color is a set of reusable colored pens designed for children. Each pen is made from recycled plastic, and the pen shell gains a second purpose after drawing. The pen body can be taken apart with a simple tool, so one pen becomes several small columnar parts. The parts can then be freely assembled through an interlocking structure. Children can move from two-dimensional drawing to three-dimensional building. Each pen measures 110 by 21 by 21 millimeters. The aim is to reduce plastic waste and to support manual skill and spatial imagination.
