Hia I did these on myself on Friday to check how long they lasted etc.
I used shellac base, cure, one layer of cream puff, cured, top coat then dipped fingers into caviar balls and cured, then another layer of topcoat over the top and cured - used quite a lot of top coat as it fell between the gaps.
I have lost half a nail on right hand today - the piece that came off was still quite flexible so think the top coat may have been too thick.
Have only lost a few individual balls though so think they are pretty secure.
Hope that helps :biggrin:
