Issey Miyake - Homme Plisse Black (pleated) Unisex Shoulder Bag

Shoulder bag has two pockets, one main pocket and a side pocket. There are no zippers on the bag and there is one button centered in the main pocket to snap shut. Shoulder strap is adjustable. Condition is brand new unused, no tags unfortunately. Color is very dark black, not faded whatsoever. Could be a rare item as I tried finding a similar Issey miyake bag online but none that is exactly like this.
