MANN FILTER Multifunction Bag Unused. Can be used as a backpack or a Boston bag, etc., depending on the purpose. I received this a long time ago, and I don't remember the details, but I believe it's a non-sale item from MANN FILTER. The condition is good, but since it's been stored by an individual, please refrain from purchasing if you are concerned about minor details. Thank you.
