Havana Wristbands?

[wishes count]

Are the wristbands the paper/plastic type you get at a fair/amusement park? Are you able to remove them? The thought of wearing it for 6 days straight I don't exactly like? Can you take it off? Get new ones as the cruise goes on? I don't really want to wear it in formal night pictures.

They are rubber bands and yes you can take them off.  We did not loose them so no idea if replaceable.  Sometimes especially my teens they asked to see their cards even with the arm bands on while enjoying the Havana pool area. Outside of the Havana pool area no reason to wear it but its just easier to put it on and forget about it.
