I have these packets I've found but instructions are long gone. They are Bicycle Cards.
First one has: 5-red/blue double sided backs, 7 black ink jokers with blue backs, and one full color joker with a blue back.
Second one has: King of Spades with blue back, and a King of Hearts with a red back, 3 blank faced blue backed, 3 blank faced red back, and 2 blue/red double sided backs.
