Helix pen / Pen

The existing ball pen’s refill is short, exhausting quickly, people have to discard spent refill and displace the new one, the consumption is great, and the one-off ball pen’s refill can’t be replaced, the pen barrel will be throw away with the refill, resulting in the huge waste and the pollution to the environment. The concept of Helix pen is to extend the refill, twisting it directly to transform the refill into a spiral pen, thus the pen barrel and the displacement of refill is no longer needed, it greatly extends the life of the pen, saving the producing material, being both thrifty and environmental friendly, and also full of fun.
