In Japan there still is a custom of using a name seal as a way of signing. A common product seen in many stores is a seal with an integrated ink refill chamber for better convenience and function. However, most of these lack a business style. The WIZ STAMP JACKET allows the user to set the refill chamber inside the simple designed aluminum body, and the shape allows the user an excellent grip. The magnet cap keeps the stamp from gathering dust, and adds a fine click feeling for better and smarter user experience. The minimal design allows users to carry the product as a casual item and also to an appropriate business scene.
