Well, I suppose it depends on the person. Personally, I wouldn't buy it. Not my cup of tea.The box itself goes in my jacket pocket or I would hand it to someone to hold. I've never had a problem with a box being crushed whenever I've performed. I suppose, if it's happened to someone one to many times, then realistically, that person should be more careful with their box and where they put it.
I mean, come on, how many times have you seen people just sit down half way during their own routine? Once the routine is over, you return your cards back into its box.
I can't b the the only one that does that?
