In daily life, cotton swabs are used in many places.However, swab rod is made of wood, and it is one-off. The swabs will be thrown away instead of being used again, so there are tens of thousands of swab rods are used up every day, causing a huge waste.
Concerning this issue, we designed a swab rod which is reusable, used together with little cotton swabs. The length of the little cotton swab is one third of the common in daily life.In this way, using one little cotton swab will save one third of the wood. Therefore, a simple swab rod design with little cotton swabs can save a lot of wood, protecting our environment.
