Greenroom Ideas Cooperation is a leather goods design brand. The products are handcrafted with needles and thread to highlight the durability and charm of leather. GR provides modernist designs to achieve function, aesthetics, and endurance.
The goal of this project was to design an ID cardholder that enhances both user experience and lifestyle through craftsmanship. The design of the multi-layered space and extendable lanyard meets the needs of switching between various spaces when working and commuting while also presenting the attributes of simplicity.
A three-layered space is created with a one-piece folding structure. One side is a simple inclined card insertion opening that shows a unique pattern; the other side is a transparent window for easy identification of documents. There is an independent space in the middle.

Extendable Lanyard​​​​​​​
The lanyard can be extended using the magnetic snaps on the forepart of the lanyard to easily swipe a card when commuting and paying. I also designed an extended strap for hanging on a bag.​​​​​​​
