In 2014, we released “PCB ART moeco,” our first B2C product line featuring PCB art goods, and we continue to cherish the spirit of challenge that drives us to blaze new trails.

■ PCB Art Eco-Bag

We commissioned ROOTOTE, a Japanese brand specializing in tote bags, to produce this large eco-bag. The fabric design was created by Denshi Gihan. Genuine printed circuit boards are affixed to both the front and back of the bag. The boards are equipped with circuits that light up LEDs via radio waves, making this a playful eco-bag.

The eco-bag features a zipper at the top. The sides of the bag include ROOTOTE’s signature “Root Pocket.” With three exterior pockets, it is a convenient and practical bag.
