The great British magician Eric Mason changed the world of mentalism with his invention: the Boon Writer "the greatest smallest gimmick in mentalism".

Some performers may find it difficult to write well with the Boon Writer for different reasons: they may find it a little bit unstable, or they feel they need a stronger grip.

The B.U.G. Writer was specially designed to adhere firmly to the fleshy pad of the thumb. Its special design and sticky surface allow you to master the use of this wonderful gimmick and still keep it absolutely invisible for the audience.
