Specially designed for travelers, SPACE BAGS shrink storage space needed up to 75%. Get more into your luggage and carry-on bags. Place the items to be stored in the pack and close all but 2" of the seal. Starting from the opposite end, roll the air out towards the opening. When fully rolled, press the seal close and store! Re-use over and over! Airtight and waterproof, seals out: moisture, mildew, dirt, insects and odors!
