The Minimalist closure is sleek and uncluttered. All of the functional infrastructure - the snaps, the screws - are hidden inside the closure so that you have the same moveable, removeable, flexible characteristics you have come to love about JUL leather closures without the glitter of metal. These closures wrap around the knitwear creating two secure options for symmetrical garments requiring a 1 inch overlap in the front, as well as for asymmetrical garments where you want to be able to layer one edge over an expanse of fabric in a garment or accessory.
