In the veins of leaves — the skeleton of human beings — a clear principle is guiding us. Take a close look at the amazing giant Amazonian lotus. The veins spread out evenly from the center, forming a dense grid. This is to say, it ensures the whole plant float lightly on the water. A wonderful geometry of nature. Based on a solid structure, we could explore outward step by step, to create a new adventure as a result. Write quietly, and be able to see clearly the direction. ROLLERBALL PEN BARREL Laban Skeleton is made of fine brass. The poetic filigree pattern shows Laban’s outstanding manufacturing technique. And moreover, it protects the transparent acrylic tube inside the barrel completely.
