I have tried literally every type of swami gimmick in existence. The invisible writer is hands down
the best. you don't have to maintain the manicure necessary for a under nail writer, you don't have
the lack of stability issue of a boon writer and it doesn't attract pocket lint. it goes on and off
with only a twitch of your fingers. I already have two, and I want one more. OH, and changing the
lead is super easy. What took soooo long?
