Masamichi Katayama‘s name may not ring any bells for some readers; however, you have most likely seen his fantastic interior design without knowing it. As a founder and head of prolific Japanese interior design firm Wonderwall Katayama is known for his bold and functional shop-fitting designs, such as designs for A BATHING APE, UNIQLO, and other international clientele. JAM HOME MADE is working once again with Katayama for their Signature Collection, this time creating an original WWMK bag, geared towards short business trips. The tote-like leather bag can easily fit a tablet, passport, stationery, and tickets, the bare minimum required for a successful business meeting. This item is available from select JAM HOME MADE retailers and the brandâ€™s own webstore.
