There are a lot of fun reasons why you may want to color code your plug stems! Maybe a pink stem means "NFS" so employees know it is part of an auction or perhaps its already been sold.   Maybe a "green stem" means talk to manager before selling or special price. Etc. 

NEW WHITE STEMS
Write on your white stems (and any of the other colors except black) using permanent black marker. We recommend a UV resistant all-weather permanent marker.
