Wet Bags are 13" wide by 14" long.The top edge has elastic sewn in the seam and then a snap strap (like umbrellas) to hold it closed. These are great for holding your soiled products without getting your anything else wet.  These greatly reduce any odors. They are also great for dirty cloths, swim cloths, toys, whatever! I recommend wringing out drenched/rinsed items as these are not truly water tight, like a baggy.  If you blow air into them, you have to compress it to remove the air, so they are fairly air tight!
