Those hides don't offer much sense of security. The doorway is too big (Imagine how you'd feel living in a house with an extra large doorway that had NO door on it?) & the interior is not deep & dark enough to feel safe to a snake that needs to hide. They also look lightweight- & while you can get away with that for some snakes, it doesn't work for all- when the snake pushes up (BPs like "back pressure" to feel snug) a lightweight hide will lift up & offer no sense of security.
Instead, I would highly recommend using something like these: (They come in different sizes, so double check your snake's approximate size when he's curled up, against the sizes available- you want hides that are just slightly larger than your snake). Reptile Basics is one source of hides like this, there are others- but I personally use many of theirs. https://www.reptilebasics.com/hide-boxes If the hide is a little too big, you can also stuff in some paper to make it cozier, while your snake "grows into it."
