I believe the nail tips you are thinking of are from 'star nail'. Also Sina do pre designed tips. I can't remember the name of the wholesaler who carries Sina products but the were in Northamptonshire. Maybe one of the midland geeks can remember what it was called? I also remember the NSI wholesaler carried pre designed tips too. Why not hand paint some hearts? It's really easy. If not, also go with the stickers they add variety and can be fun too.
