This sample is 8x5.5 inches and represents a match to the colour clarified in the product description. 
By having bigger samples and eliminating the need for a sample book it reduces the amount of cardboard that is wasted and used overall reducing our carbon footprint. 
Actual colors may vary. This is due to computer monitors displaying colors differently and the interpretation of the colour.
