Custom made replacement function button badges for Harman Kardon cassette decks.  These are made of .02" sublimated satin silver aluminum and come with double-sided tape on the back for easy attachment.  The badges were custom made and should fit each button suitably. The purchase price will include six badges as pictured.   

Each badge measures 21mm in height and 2.4mm holes have been drilled as shown to accommodate function lights.
Please to be sure to measure the keys on your deck to make sure that the 21mm height is correct.  I have had some feedback that 21mm is too large but others seem to fit perfectly.  There may have been some variance in the keys during the production period.
