This pack includes 8 travel roll-up storage bags, with 4 medium and 4 large sizes. The medium bags measure 71 x 51 cm and are suitable for 8-10 sweaters, while the large bags measure 81 x 61 cm and can hold 10-12 sweaters. The unique roll-up design effectively squeezes out air, and the valves prevent air from re-entering. These versatile and reusable bags are ideal for storing clothes, bedding, pillows, socks, and seasonal items. They can be easily washed, folded, and reused multiple times. Designed for travel, these bags do not require a vacuum or pump; simply pack, zip, and roll to expel air through the bottom valves. The transparent design allows for quick luggage checks at airports, making them TSA approved and compliant. These superior-quality bags protect your belongings and reduce item size by up to 80%, creating extra suitcase space. Made from thicker, tear-resistant material with a convenient and quick-sealing zipper.
