Nipple shield storage

NJshore40

Nipple shield users...how do you store it when not using?  I have lost a few since its clear in color.  Since then ive been storing in a ziplock baggie with a wet papertowel but I'm sure there has to be a better way.  What do you do when you are out and about for storing/cleaning inbetween use?  I am wondering if there is something similar to a dental retainer case that is bright in color so its not misplaced.  Any ideas?
