There are a lot of nail writers and swami gimmicks on the market, but these are the ones that Richard Osterlind used on his Mind Mysteries video series - Sam Dalal's Swami Gimmick.
Each package contains four gimmicks (that's right - four!), a generous supply of extra leads, and 32-page illustrated booklet with many ideas, handling tips and routines.
If you've seen the miracles that Osterlind creates with this simple but powerful tool on his Mind Mysteries videos, you already know that this is quite a bargain.
