A refill pack of 6 organic cotton tissues to use when your orginals are either in the laundry or you just need to stack up on a new batch. Fill your empty LastTissue case with your new stack of tissues, and place the silicone barrier on top. Start using by pulling the tissues from the bottom slot. Place the used ones on the top, and the barrier will keep the used ones separated from the new. When they're all used you can toss them in with your laundry and they come out even softer than before. Dry them, fold them, and pop them back into the case. Each tissue can be reused 500 times, so with 6 tissues you'll eliminate 3000 single-use tissues! The tissues are made of organic cotton.
