Snakes cannot get "stuck" in cardboard rolls from wrapping paper, paper towels or toilet paper: yes, they can be hard to get out when YOU want them to, but
they won't get "stuck". If they did (ie. you cannot wait for them to emerge) it's VERY easy to tear the roll open along the spiral lines where they're put together.
Of course that does destroy the roll, but they're easy to come by, eh?
What you SHOULD always worry about (as far as snakes getting stuck) is something they cannot back out of because it's wider at one end (so they enter) and
gets narrower (so they can't back out). Also, materials that cannot be torn apart (like cardboard) should be carefully assessed before using: many aquarium
decorations ("castles" etc) that are designed for fish to swim thru are death traps for snakes, & also have sharp edges inside. Likewise, cholla logs are deadly.
