If your attention tends to stray for even a second, why not master a musical instrument - courtesy of Suck UK - at your desk? A musical instrument that doesn"t involve heavy breathing, or coordination, or timing of any kind. You needn"t even leave your chair. You"ll impress others - and maybe bring your office together in an impromptu, team-building singalong. And then you can use it to underline your ever-growing To Do List. Plastic ruler with printed finger markings and note positions. Sliding the ruler up towards the edge of the desk alters the note, enabling you to play anything from Abba to ZZ Top, just like this young gentleman...This may be the only product in the world you can use to draw straight lines in your diary, and then to play House of the Rising Sun on the edge of your desk. (We"ve tried ... you just cannot draw a straight line with a tuba!) Pack contains 1 musical ruler and 1 guide to ruler playing.
