Photobert CheatSheet for Nikon SB-600 Speedlight is laminated, waterproof and very sharp and clear. It's like having the manual on a card - but better! Almost everything in the Nikon manual is on this one card.
This CheatSheet is an "easy to take with you", invaluable quick reference.
It's printed on both sides of a full-sheet of paper that's laminated with a heavy 10-mil laminate and is folded in thirds. When folded it's about 4.5 x 8" so it stores easily.
