Just a Mini swatch I use on my Ace Pro's and on my Server/Storage rack. 

I print two: One as a stock label and the other gets moved to the Ace Pro Slot when in use.

I use a magnet on the back of the swatch and one on the Ace Pro in a crude manner using CA glue.

I use a label maker to put the Color, Type, Brand, and Temperature range. 

10x2mm magnets are Ideal.
