Water Wipes are a fresh natural product, free from chemicals and preservatives. Because of this, they are best used before the end of: See printed exp. Use within 4 weeks of opening. As with all fresh products, reclose the label after taking the wipes you need. Store in a cool dry place. Please never cut open the individual pack or transfer the wipes to another container as the integrity and purity of the pack will be compromised and may cause the wipes to discolour. Because we don't use chemicals to bind the liquid to the wipes like others brands, the water can sometimes migrate to the bottom of the pack, making the top wipes feel a bit dry. To remedy this, simply turn the pack over and squeeze it a few times and that will redistribute the water throughout the wipes. Do not flush.
