I use dave powell pencil thumb writers all the time and find this product almost invisible
surrounded even at close proximity to the spectator. It has options to move the lead to suit your
thumb. Gave 4 stars as its a bit pricey, the lead is small requiring more frequent changes than the
old vernet thumb writers and is a more difficult to ditch as the fit is too snug. This is a must try
for all mentalists who do swami writing in their act.
