Triple your storage space while you pack away your clothes, blanks, quilts and other personal items safely and conveniently. All you need to do to seal the bags securely is use your vacuum cleaner to suck out all the air and zip the slider across. An airtight and waterproof seal is automatically created. These bags are manufactured with high quality materials that are designed for long-term storage. Once sealed, the bags are anti-pest, waterproof and anti-mildew and your clothing and personal items are safe and protected until you need them again. It is recommended that clothes and other items being stored are clean and dry before they are packed into the bags. It is not recommended that items with feathers be stored in the bags. Be careful not to prick the bags with sharp objects. These bags are not designed for food storage or the transportation of pets. Caution should be used when closing the zipper to make sure that a tight seal has been created.
