My 16's are tucked away in my wallet as well. If you are afraid of damage, take zip locks with you and tuck them in the zip lock. I have done that in case they get wet. I have never had an issue with them getting damaged. Ever. I do believe it says do not laminate on the passes themselves. I remember when I was little and we got season passes. The long ones with all your information filled in by yourself and the wheel chair rental area laminated them for a fee?? Is my memory off here? Anyhow, they are sturdy considering what they are made of. You could also get a plastic badge holder like they use for security officers or hospital workers.
