The 4 decorative markers in bright, super-opaque neon colours (pink, orange, light blue,yellow) can be removed from wipeable, closed surfaces with a damp cloth.
Totally cool, e.g. for embellishing mobile phone covers, mirrors, cups, plastic boxes or foils.
The markers also write well on rough surfaces, but cannot be wiped off.
This is how it works: Simply shake the pen, press the lead hard several times and start drawing! Line width: 2 mm
