The artwork was commissioned from KALON DESIGN STUDIO, who provided the following comment: "The artwork symbolizes the number 8, which is considered a lucky number representing prosperity. The hot air balloon shaped like the number 8 was created with the hope that mowl® will continue to soar to greater heights."

We meticulously laser-engraved each raw unit on both sides, dedicating over an hour to each side using the smallest laser settings. Through repeated trial and error, we discovered a special technique for engraving on the raw material. This unique engraving changes appearance depending on the light, sometimes appearing as a black engraving and other times showing a white logo, allowing you to enjoy different visual effects in various environments.
