Taiwan DNA pen selected “Atrophaneura horishana” and “Agehana maraho” from DNA models as the pattern. On one hand, it can echo Taiwan’s “butterfly kingdom”, on the other hand, the unique beauty of Taiwan creatures can show by the dynamic gesture. The pens can replace cartridge and write smoothly, which is durable. The pattern is beautiful, unique and modern. With the beautiful box, there are the introductions of those two butterflies on the back, which is a featured generous and decent gift in Taiwan.
