Only a magician will want to buy a Sharpie that doesn't write and know why and what they want to do with it.
This is not a dry out Sharpie that you left under the sun, or put nail polish on the tip so it doesn't write. If you have done that you know it will still leave a mark as you write with it.
The No Write Sharpie has a rubber pen tip that looks like it's still wet and feel smooth on paper. You can allow a spectator to randomly mark on any printed matter without looking at it and seemingly leave a random mark for a chosen object you want them to choose.
The set comes with a real normal Sharpie and the No Write Sharpie, plus ideas for using it with lottery tickets, bingo cards and cross word puzzles.
