When the pandemic first started up we reevaluated a number of our supplies at our rental properties. One thing we changed up was our sponges. We used to use these all-natural expanding sponges (which we still love) but were curious if there was a way of providing something even more sanitary.
These vacuum-sealed sponges have been a good solution. Small, so that they don't feel like as much of a waste when used only for a 1-2 week stay. Flat-packed, so they're easier to ship and store, and of course well sealed so each guest knows they are getting a totally fresh sponge.
