This is a Milanese Loop band for Apple Watch, which is now discontinued. It's for 45mm, but is also compatible with other sizes. It's a free size and uses a magnetic closure, allowing for infinite adjustment. I bought it about 3 years ago, but I haven't used it much, so I'm selling it. There is no box. Only the band itself. Please understand that this is a used item before purchasing. - Color: Graphite - Material: Stainless steel mesh - Compatibility: Apple Watch 44mm, 45mm
