The set includes four highlighter pens with bright and highly opaque neon inks. Dried or still damp, the ink can be wiped off any wipeable and sealed surface with a moist cloth. This way there is a wide range of possible uses: for embellishing mobile phone cases, mirrors mugs, plastic boxes or clear film. The pens can also be used on abrasive surfaces such as cardboard. However , the ink cannot be wiped off there again. Prior to use the pen has to be shaken and the tip has to be firmly pressed onto a surface several times until the tip is filled with ink. The set is wrapped in a transparent zipped bag that also can be embellished with the pens.
