* Please note:  these large single letter initials are designed to be used on the stainless steel travel mugs and personalized sippy cups and straw cups.  If you want them to be used on can or bottle coolers, that is fine too.  However,  each letter takes up all usable space on can coolers so they wouldn't work with a ribbon (without is fine though).  On bottle coolers, there is plenty of room for the letter and a ribbon.
