This card should be supplied with a magnifying glass

This card is 60% the size of a normal compass deviation card. The PAI-700 compass I ordered came with a normal sized card, though the PAI-700 product description does NOT indicate a compass correction card comes with it.
That this too small paper card costs $.70 is definitely an overcharge, IMHO.

Q: What are the dimensions of this compass deviation card?
