10 Pack of replacement Humidity Hut Sponges

Sponges are super easy to sterilize- saturate them, place on a small, microwave safe dish and microwave for a few seconds. Be CAREFUL! They will be very hot when you remove them. You can also saturate with F10 solution, let stand for 10 minutes, rinse and you are ready to go!
