It may be that the mylar ones were not manual-punch
friendly, so you could
make a duplicate to use while you waited for the proper
spare to arrive.
There's a photo of a mylar card at

The Mylar cards were VERY thin. I always assumed they were
attached to a slightly thinner than usual paper card for
punching, then separated from the paper to put into the ROS
system.
That picture you linked to is the best photo I've seen of a
/30 ROS card!
