1. Clothes and quilts should be completely dry before being placed in the bag. 2. Please do not touch the nail or needle directly to avoid piercing the bag. 3. Please avoid using feathered items in the bag, as there will be some hard thorns. When the air is drained, the thorn may protrude from the item to puncture the bag. 4.
