NWT Biaggi Zipsak Underseat Boost Cobalt Blue

New in box, never used expandable under-seat carry-on. Super versatile! Starts off as a small easy-to-store pouch, and opens to become a 4-wheeled carry-on that slides comfortably under the airplane seat in front of you. It can also expand a full 5" upwards, to become a full sized TSA approved carry-on. It can also slide over the handle of another rolling suitcase for easy carrying as pictured.
