A writing instrument includes a first reservoir for dispensing a first fluid having a first property of reflectivity. A first tip member is in fluid connection with the first reservoir. The first tip member has an end with a size and shape that corresponds to a response area of the response form. A second reservoir can be used for dispensing a second fluid, which is capable of modifying the first property of reflectivity when covering the first fluid. A second tip member is in fluid connection with the second reservoir. The second tip member has an end with a size and shape that corresponds to the response area of the response form.

A writing instrument such as a pen or stylus, that is capable of writing contemporaneously in different physical characteristics, such as color and visual appearancethat is, without the need to switch out different cartridges to write in different characteristics; as well as to an ink device for such a writing instrument, such as a multi-cartridge tip having multiple nibs, where the multiple nibs can be used to write on a substrate contemporaneously. A writing instrument herein can be configured to write at a substantially perpendicular angle to the substrate, or slightly angled for ease of a user's hand position. A writing instrument that encompasses both electronic and manual (ink) features is also contemplated.
