With as big a magnify glass that I can find I can see the caps and after some effort get them on top of the existing caps but I can not get them to stay there.  I have tried every small tweezers I can find, even very small ones from a little Swiss army knife, no luck.  Any suggestions on how to keep them there would be appreciated.  Thank you  73
