• The Flex-Fletch Ultra-Soft Kisser Button is conveniently split for quick installation.  Simply open the split and place in the desired spot on bowstring.
  
• Secure it in place using a small amount of Flex-Bond Adhesive or similar glue.  Speed dry times by closing the kisser after the flex-Bond has been applied then separate the sides and blow on it for 5 to 10 seconds.  Re-close and hold in place for 1 minute.  Let cure for 24 hours.  This is the best method. If you are in a hurry, you may also use a tiny drop of cyanoacrylate glue commonly know as super glue.  Be sure to use only a tiny amount.  Too much will cause unnecessary dry time.
  
• The specially compounded ultra flex material is designed to fit all bowstrings but in a very few cases the bowstring will be slightly too large.  In this case you will need to use a suitable size drill bit to enlarge the hole before installation and adhesion.
