The minimalist beauty of YStudio’s designs, allow the quality of the materials used to become apparent. The brass & walnut construction of this pen case lends it a look of refinement, providing a stylish home for your pens & pencils. Simply rotate the brass end to open the case. Selector’s Notes: Over time the pen case will develop character; the wood will darken, and the brass will patinate adding layers of depth and charm to the piece.
