Just a word of caution, especially if your snake gets unbelievably huge or if you are getting the smaller sizes. There have been stories of snakes getting trapped in those holes and not being able to get out until you break them.. So do keep watching on the size of the snake relative to that hole the moment it starts touching something on both sides I'd get a bigger one. But they do make good humid hides, just make sure they are regularly cleaned. I forgot to scrub all of them down regularly and merely changed the substrate/moss inside and I ended up getting mold in them. Scary!
