About Alter Sleeves

Who are Alter Sleeves? Hello! We are Alter Sleeves, the only producer of the world's first print-to-order custom protective inner sleeves for Magic: the Gathering. Following our successful Kickstarter in April, we got to work making sure the product could be as good as possible before fulfilling our backer rewards*, and as of December 2nd, 2019 we opened to the general public.
